2,6-Diethyl-N-Propoxyethyl Aniline
2,6-Diethyl-N-Propoxyethyl Aniline — widely traded under the abbreviations PEDA or CDEPA — is a single-purpose, high-value intermediate in the chloroacetanilide herbicide chain. Its entire commercial reason to exist is one downstream molecule: Pretilachlor, the pre-emergence herbicide that protects wet-seeded rice from grassy and sedge weeds across South and Southeast Asia.
Chelora Chemicals sources PEDA for agrochemical technical manufacturers, formulators and toll processors, in drums, IBCs and bulk tanker quantities, with a batch COA and safety data sheet on every consignment.

What PEDA is used for
PEDA is built by reductively alkylating 2,6-diethylaniline with 2-propoxyethanol, which installs a propoxyethyl chain on the amine nitrogen while leaving the two ortho ethyl groups on the ring untouched. That single N-alkylation step converts a general-purpose aniline into a dedicated agrochemical intermediate: the secondary amine it produces is exactly the nucleophile that chloroacetyl chloride needs to build Pretilachlor.
Unlike a multi-outlet intermediate that feeds pigments, pharmaceuticals and agrochemicals all at once, PEDA is a captive, single-application molecule. Almost every kilogram produced worldwide is consumed on-site or shipped directly to a Pretilachlor technical plant. That narrow focus is precisely why buyers value a supplier who can confirm the material, the assay basis and the delivery window before committing tonnage.
Where it sits in the family of N-alkylated anilines
PEDA belongs to a small family of N-alkylated 2,6-dialkylanilines that each feed one specific chloroacetanilide herbicide. The pattern is the same across the family: an ortho-disubstituted aniline is N-alkylated, then chloroacetylated to the finished active:
- 2,6-Diethyl-N-(2-propoxyethyl)aniline (PEDA / CDEPA) — this product. Feeds Pretilachlor, used in wet-seeded rice.
- 2,6-Diethylaniline (2,6-DEA, CAS 579-66-8) — the parent aniline and feedstock for this product, also the feedstock for Alachlor and Butachlor via different N-alkyl groups.
- 2-Ethyl-6-methylaniline — the parent aniline used in the Metolachlor / S-metolachlor chain, a close cousin by role rather than by structure.
If your specification calls for the parent 2,6-diethylaniline instead, or for a related N-alkylated aniline used elsewhere in the chloroacetanilide family, tell us the exact CAS number or downstream active you are building and our technical desk will confirm the correct material — see our full aniline and agrochemical intermediate range.
Appearance and handling character
Commercial PEDA ships as a pale yellow to amber, oily liquid at ambient temperature — the propoxyethyl chain and the two ortho ethyl groups between them keep the molecule liquid well below room temperature, unlike some of the simpler chlorinated anilines that crystallise. It is practically insoluble in water and miscible with common organic solvents. As with other secondary aromatic amines it can darken slowly on prolonged exposure to air and light. Because this is a lower-volume, specification-driven material, published independent physical-constant data under this CAS number is limited — see the note under the property table below, and treat your supplier's batch COA as the reference document.
| Parameter | Typical value |
|---|---|
| Appearance | Pale yellow to amber clear liquid |
| Assay (GC) | 97.0% min |
| Moisture (KF) | 0.5% max |
| Residual 2,6-diethylaniline | Reported per batch |
| Colour (APHA) | Reported per batch |
| Non-volatile residue | Reported per batch |
Important: the figures above describe commercial-grade material offered for planning purposes only. The batch certificate of analysis is the governing document. If your Pretilachlor process is sensitive to residual free amine or to colour carry-through, send us your specification and we will quote against it rather than against a generic grade.
| Property | Typical / indicative value |
|---|---|
| Physical state | Oily liquid at ambient temperature |
| Appearance | Pale yellow to amber |
| Relative density | ≈ 0.94 – 0.97 (typical for this class) |
| Boiling behaviour | High-boiling; typically distilled under reduced pressure |
| Flash point | > 110 °C (closed cup, typical) |
| Water solubility | Practically insoluble |
| Organic solubility | Miscible with alcohols, ketones, aromatic & chlorinated solvents |
| Odour | Faint amine odour |
Data note: independent, publicly published physical-constant data specific to CAS 61874-13-3 is limited, because this is a lower-volume, single-outlet intermediate rather than a widely traded commodity chemical. The values above are typical for material of this structural class and are offered as orientation only — always work from the SDS and COA issued with your specific batch rather than treating these as verified constants.
A single molecule with one job to do
PEDA does not spread across colour chemistry, pharmaceuticals and plastics the way a general-purpose aniline does. Nearly its whole demand curve is one herbicide's manufacturing schedule.
Pretilachlor manufacture
Chloroacetylation of PEDA with chloroacetyl chloride gives Pretilachlor technical, a chloroacetanilide herbicide used almost exclusively for pre-emergence weed control in transplanted and wet-seeded rice.
- Nearly the sole commercial outlet for this molecule
- Assay and residual-amine limits are the buyer's key checks
- See our agrochemical intermediate range
Backward integration for herbicide producers
Formulators who currently import Pretilachlor technical, or who buy chloroacetylated product from a toll processor, use merchant PEDA to bring the chloroacetylation step in-house without having to run the upstream N-alkylation themselves.
- Shortens the internal value chain by one step
- Reduces exposure to a single upstream supplier
- Useful for import-substitution programmes
Custom & specialty amide/urea synthesis
The secondary aromatic amine nitrogen is a general-purpose acylation site. Beyond Pretilachlor, fine chemical customers use PEDA in small volumes for custom amides, ureas and related N-aryl derivatives where the 2,6-diethyl, N-propoxyethyl substitution pattern is specifically required.
- Available in trial and laboratory quantities
- Acylation, sulfonylation and carbamoylation chemistry
- Ask our technical desk about non-standard grades
Analytical & reference standards
Pretilachlor manufacturers, formulators and residue laboratories occasionally need PEDA itself as a process intermediate reference or degradation-pathway marker for method development and quality investigations.
- Small pack sizes available
- Analytical documentation on request
- Not supplied as a certified reference material
Toll manufacturing & contract synthesis
Where a customer supplies their own 2,6-diethylaniline, we can arrange reductive-alkylation toll processing to PEDA through our qualified production partners, keeping the intermediate under the customer's own material chain of custody.
- Customer-supplied feedstock accepted
- Batch traceability maintained throughout
- Ask about confidentiality and NDA terms
Contract & scheduled supply
Pretilachlor manufacture runs to the rice-sowing calendar rather than a flat annual demand curve. Most PEDA buyers want tonnage released ahead of the wet-seeding season rather than in one shipment.
- Seasonal contracts with scheduled call-off
- Price held across the contract period
- Pre-season stock build available on request
How we supply PEDA
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. For a low-volume, single-application intermediate like PEDA, where only a handful of plants worldwide run the N-alkylation step at commercial scale, that independence is exactly what a buyer needs — we are not tied to one captive unit's output or schedule.
We place your order with a qualified producer matched to your assay, your residual-amine tolerance, your price point and your delivery window against the rice-sowing calendar.
Because the supply base for this specific intermediate is narrower than for a commodity aniline, we work early with customers to lock in seasonal tonnage well ahead of peak Pretilachlor production, rather than leaving sourcing to a spot enquiry.
- Specification confirmed against the CAS first. We verify you need 61874-13-3 (PEDA/CDEPA) and not the parent 2,6-diethylaniline or a different N-alkyl aniline, before we quote a price.
- Batch COA shared before dispatch. You approve assay, moisture and residual-amine content against your own spec while the material is still in our warehouse.
- Honest data, not inflated data sheets. Where independent physical-constant data for this specific CAS is thin, we say so rather than presenting estimates as verified fact — your SDS is the authority.
- Pre-shipment samples for qualification. New account or new source, your R&D or process team runs a lab-scale chloroacetylation before the full quantity ever moves.
- Seasonal planning built in. We plan call-off dates around the wet-seeded rice sowing calendar in your target markets, not around a generic delivery slot.
- Export machinery handled in-house. Hazard classification, packing, labelling, freight booking and customs paperwork are ours to manage.
- Consolidation onto one bill of lading. Ship PEDA alongside 2,6-diethylaniline or other intermediates from our range — one invoice, one shipment, one counterparty.
Packed the way your plant receives it
As a liquid intermediate handled in relatively modest batch sizes, PEDA is typically packed in drums or IBCs rather than bags. Tell us your charging method and destination and we will quote the pack format that suits it.
Mild steel / lined drums
UN-certified drums, the standard format for liquid amine intermediates moving by sea. Internal lining specified where your process is sensitive to trace metal pick-up.
IBC totes
Intermediate bulk containers for customers taking a pallet at a time, reducing per-litre packing cost and the number of drum changeovers on your charging line.
Bulk liquid transport
For contracted seasonal tonnage, flexitank or ISO tank movement cuts packing cost and handling to a minimum. Arranged where destination infrastructure supports it.
Samples & trial packs
Laboratory samples and pilot quantities dispatched by courier so your process team can qualify the grade and trial your chloroacetylation step before committing to volume.
Incoterms to suit you
Quoted on the Incoterm your purchasing team works to. Ocean, air and road freight arranged end-to-end with documentation filed before booking.
Sowing-calendar despatch
Pretilachlor demand tracks the wet-seeded rice calendar. We hold contracted tonnage and release it against your production plan ahead of each sowing season.
Handle it as a secondary aromatic amine
No harmonised GHS classification is currently listed for CAS 61874-13-3 in the major public regulatory inventories at the time of writing. That is not the same as "no hazard" — it is a secondary aromatic amine, a structural class that is routinely irritating to skin and eyes, capable of some skin absorption, and toxic to aquatic organisms. Handle it with the same discipline you would apply to any aniline derivative, and treat the SDS supplied with your specific consignment as the authoritative document for hazard statements, PPE selection and emergency response — do not assume a hazard profile that has not been confirmed on your paperwork.
General hazard picture for this structural class
~H302May be harmful if swallowed (typical for this amine class).~H312May be harmful in contact with skin.~H315May cause skin irritation.~H319May cause serious eye irritation.~H411Toxic to aquatic life with long lasting effects (typical for aromatic amines).
The statements above are marked with a tilde because they describe the general hazard pattern of the structural class, not a confirmed, harmonised classification for this exact CAS number. Always read the specific SDS issued with your batch and follow the manufacturer's own classification, which may be more or less restrictive than this general picture.
Spill & emergency orientation
Plan your response before the drum arrives. The points below are orientation for your emergency planners — sections 4, 5 and 6 of the SDS are the authoritative instructions and should be posted at the point of use.
- Contain, do not hose to drain. The material is expected to be toxic to aquatic life. Bund and collect a liquid spill into a labelled container; never wash it to a drain or watercourse.
- Use absorbent for a liquid spill. Inert absorbent (sand, vermiculite, commercial spill granules) rather than water is the standard first response for an oily aniline derivative.
- Assume some skin absorption. Contaminated clothing is a continuing exposure route — remove it promptly and wash the skin thoroughly.
- Have the SDS with the casualty. Aromatic amines can affect blood chemistry in some individuals; the treating clinician needs the product identity and CAS number in hand.
- Ventilate enclosed spaces. A confirmed odour or vapour build-up in a poorly ventilated tank or drum store should be treated as a signal to improve ventilation, not tolerated.
Storage
- Cool, dry, well-ventilated store, away from direct sunlight and heat sources. As a liquid it should be kept in sealed drums or IBCs to limit moisture pick-up and slow oxidative colour drift.
- Keep containers tightly closed. Air and light drive the pale-to-amber colour drift typical of secondary aromatic amines.
- Segregate from oxidising agents, strong acids and acyl chlorides. As with any secondary amine, uncontrolled contact with an acylating or oxidising reagent should only happen inside a designed reaction, not in storage.
- Bunded floor. Standard practice for a liquid organic intermediate that is toxic to aquatic life — a spill should never be able to reach a drain.
- Shelf life is typically 12–24 months in sealed original packing under these conditions. Re-assay before use after long storage.
Handling & PPE
- Closed transfer where practical. Pump or gravity-feed from drum or IBC rather than open pouring, to limit vapour and skin contact.
- Chemical-resistant gloves and splash-proof eye protection as a baseline for any liquid aniline derivative, regardless of the exact classification on the label.
- Local exhaust ventilation at any point where the drum or reactor is opened, particularly in a warm climate where vapour pressure rises.
- Wash promptly after skin contact, and treat contaminated clothing as contaminated until laundered separately.
- Never discharge to drain or watercourse. Collect any spill or rinse water as regulated chemical waste rather than assuming it is safe to dilute.
Transport
We classify each PEDA consignment individually against the current transport regulations for the shipping mode and destination, and file the correct paperwork before booking. The applicable UN number, class and packing group — if any apply to your specific shipment — are confirmed on your shipping documents and SDS. Ask us for the current transport paperwork when you plan the shipment.
What travels with every consignment
For a specification-driven intermediate feeding a single downstream process, the paper trail matters as much as the drum. Verifying what the source plant sends is precisely the work you are buying from a supplier.
Certificate of Analysis
Batch-specific assay by GC, moisture by Karl Fischer, colour and residual free-amine content — checked against your purchase specification before we release the goods.
Safety Data Sheet
Full 16-section SDS covering hazards, exposure controls, handling, storage, spill response, toxicology and disposal — issued in the language your destination requires.
Transport documentation
Correct classification, packaging and labelling for the shipping mode and destination, with the dangerous-goods declaration filed before the container is booked wherever it applies.
Certificate of Origin
Chamber-attested where required, plus preferential-origin forms where a trade agreement gives your import duty relief at the destination.
Third-party inspection
SGS, Intertek or Bureau Veritas sampling and inspection arranged on request before loading, giving you independent verification of what actually ships.
Retained & pre-shipment samples
Pre-shipment samples carry the same COA as the commercial lot, so what your laboratory qualifies is exactly what arrives. Retention samples held against the batch.
Three steps from feedstock to finished herbicide
PEDA sits in the middle of a short, linear value chain. Understanding the two steps either side of it explains why the assay and the residual-amine figure on the COA matter more here than they would for a general-purpose intermediate. The pattern below is the general industrial route, not a process disclosure.
Start with the parent aniline
2,6-Diethylaniline (2,6-DEA) provides the ortho-diethyl-substituted ring. The two ethyl groups create the steric environment the downstream herbicide needs.
N-alkylate to PEDA
Reductive alkylation with 2-propoxyethanol installs the propoxyethyl chain on the amine nitrogen, giving this product — a secondary aromatic amine ready for acylation.
Chloroacetylate
Reaction with chloroacetyl chloride converts the secondary amine into the chloroacetamide that defines the chloroacetanilide herbicide class, giving Pretilachlor technical.
Formulate to product
Pretilachlor technical is formulated into emulsifiable concentrates and granules for sale into wet-seeded and transplanted rice markets.
Why the assay and the residual amine matter so much here
Because PEDA has essentially one buyer-side use, the specification questions a Pretilachlor manufacturer asks are narrower and sharper than they would be for a multi-outlet aniline:
- Residual 2,6-diethylaniline competes for the chloroacetyl chloride in the next step, consuming reagent and generating a related but off-specification by-product.
- Moisture reacts with chloroacetyl chloride directly, wasting reagent and generating hydrochloric acid in the batch — the same sensitivity seen across the wider chloroacetanilide family.
- Colour carry-through from an oxidised batch of PEDA can show up as colour in the finished Pretilachlor technical, which formulators specify against.
- Consistency batch to batch matters more than headline purity alone, since a chloroacetylation plant tunes its reagent stoichiometry to a known feed quality.
That is the reason we quote against your written specification rather than a generic "97% technical" grade, and the reason the batch COA is shared for approval before dispatch rather than sent with the invoice.
| Stage | Material |
|---|---|
| Feedstock aniline | 2,6-Diethylaniline CAS 579-66-8 |
| This product | PEDA / CDEPA CAS 61874-13-3 — this page |
| Finished active ingredient | Pretilachlor CAS 51218-49-6 |
If your process runs from the parent aniline or you need a related N-alkylated aniline elsewhere in the chloroacetanilide family, we supply those as well — see our full aniline and agrochemical intermediate range. Send us the CAS number or the downstream active and we will confirm the correct material before quoting.
What actually moves the price of this intermediate
PEDA does not trade on an open commodity market. Its price and availability track one herbicide's production plan far more closely than a general aniline's would.
One demand cycle, tightly seasonal
Because demand is concentrated in Pretilachlor manufacture, PEDA orders cluster ahead of the wet-seeded rice sowing windows in South and Southeast Asia rather than spreading evenly across the year.
- Quote well ahead of the sowing season
- Spot buying at peak season costs materially more
- Seasonal contracts smooth the exposure
Upstream feedstock
The route back to PEDA runs through 2,6-diethylaniline, ethylbenzene / ethylene and propoxyethanol chemistry. Movements in these feedstocks and in the hydrogenation catalysts used for the N-alkylation feed through within a quarter or so.
- 2,6-Diethylaniline price sets the floor
- Catalyst and energy cost weigh on the alkylation step
- We flag feedstock-driven moves in the quote
Narrow supply base
Only a limited number of plants worldwide run this specific reductive alkylation at commercial scale. That concentration means a single plant turnaround or feedstock disruption can move the market more than it would for a widely produced commodity aniline.
- We qualify more than one source where the market allows it
- Qualify an alternate source before you need it
- Ask us about dual-source or backward-integration options
End-use regulatory pressure
Pretilachlor's own regulatory status varies by country, and this shapes downstream demand more than any direct restriction on the intermediate itself. Confirm your destination market's agrochemical registration position before committing to a large contract.
- Herbicide registration status varies by market
- Confirm the current position before large orders
- We flag known regulatory shifts when we are aware of them
Pack format
Cost per kilo falls from drums to IBCs to bulk liquid transport as order size grows. For a seasonal buyer, matching pack format to your storage and charging capacity keeps the landed cost sensible.
- Drums suit trial and smaller orders
- IBC or bulk liquid suits contracted seasonal tonnage
- We help you choose based on your tankage
Freight & routing
Destination and Incoterm move landed cost as much as the ex-works price does, particularly where the shortest routing to a rice-growing region runs through a port with limited liquid-bulk handling capacity.
- Compare on landed cost, not ex-works
- We route to fit your destination infrastructure
- We quote FOB, CIF, CFR or DDP as you prefer
| If your end use is… | Specify |
|---|---|
| Pretilachlor manufacture | High assay with tight residual-amine and moisture limits |
| Backward-integrated formulator | Consistent colour and assay, batch-to-batch reproducibility |
| Custom amide/urea chemistry | Moisture the critical parameter; colour usually secondary |
| Reference / analytical use | Small pack, full analytical documentation pack |
Not sure which column you are in? Describe the reaction you are running and our technical desk will recommend the grade — including telling you when a standard commercial specification would do the job just as well as a tighter, costlier one.
Support that goes beyond shipping the drum
What our technical desk will do
- Match a grade to your reaction. Tell us the chloroacetylation step you are running and we will recommend the specification — and say so plainly when a tighter, costlier grade would add nothing.
- Be straight about data gaps. Where independent physical-constant or hazard data for this specific CAS number is thin in public literature, we tell you that rather than presenting an estimate as a verified fact.
- Advise on handling and storage for your site conditions, including practical guidance for a lower-volume liquid intermediate stored in drums or IBCs rather than bulk tankage.
- Review your specification before it goes into a contract, so you are not locked into a limit that no plant can consistently hit.
Regulatory & compliance notes
- Confirm the destination's chemical inventory status. Chemical inventory listings differ between regions; confirm your obligations under the applicable inventory regime for your import volume — we will supply the identity data you need for that filing.
- Confirm the downstream herbicide's registration status. Pretilachlor's own agrochemical registration varies by country; your regulatory team should confirm the position for the market you are supplying into.
- Import controls vary by destination. We check destination requirements before quoting rather than after you have raised the PO.
- Transport classification is assessed per shipment. We confirm the applicable transport category for your specific route and mode before booking.
None of the above is legal advice — your own regulatory affairs team owns the final compliance position for your import and your workplace. What we commit to is giving you accurate product identity data, an honest account of what is and is not publicly verified about this material, and complete documentation to work from.
