Ethylamine
Ethylamine is a primary aliphatic amine most widely known as the precursor to triazine herbicides, including atrazine and simazine, two of the most extensively used selective herbicides in global agriculture. It also finds broad application in rubber-product manufacturing and general organic synthesis, with roughly 80 million kilograms of ethylamine and related simple amines produced annually worldwide.
Chelora Chemicals supplies ethylamine as liquefied compressed gas or as aqueous solution (commonly 70% w/w) to agrochemical manufacturers, rubber processors and fine chemical houses worldwide, with a batch COA and full dangerous-goods documentation on every consignment.

What Ethylamine is used for
Ethylamine's single largest application is as the nitrogen-donating building block for triazine herbicides — atrazine and simazine chief among them — which have been staples of selective pre-emergence weed control in maize and other row crops for decades. The ethylamino group installed via this amine is a defining structural feature of the triazine herbicide family.
Beyond herbicide manufacture, ethylamine is used in rubber-product manufacturing (as an accelerator or intermediate in certain rubber-chemical routes) and more broadly across organic synthesis and the chemical industry wherever a simple, reactive primary amine is needed. Industrially, ethylamine and its close relatives are produced at a scale of roughly 80 million kilograms per year via oxidative amination of ethanol with ammonia.
Appearance and handling character
As the anhydrous product, ethylamine is a colourless, flammable gas with a strong fishy, ammoniacal odour, condensing to a liquid around 16–20 °C or under pressure. It is fully miscible with water, and both the gas and its aqueous solutions (commonly supplied at 70% w/w) are flammable and irritating to eyes and the respiratory tract.

How we supply Ethylamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. We own no amination plant — and on a gaseous, flammable reagent like this one, that independence lets us find the source that can actually deliver your specification, your pack format and your delivery window under the correct dangerous-goods controls.
We place your order with whichever qualified producer best matches your assay, your pack format, your price point and your delivery window.
- Specification and pack format confirmed first. We check whether your process needs liquefied gas or aqueous solution, and at what concentration, before we quote a price.
- Batch COA shared before dispatch. You approve the assay and concentration against your own spec while the material is still in our warehouse.
- Honest lead-time guidance. As a flammable, pressure-vessel-documented reagent tied to a seasonal agrochemical market, sourced lots can take longer than a bulk commodity — we tell you the realistic timeline up front.
- Hazard classification confirmed against the batch SDS. This compound is an extremely flammable gas and a respiratory/eye irritant — we verify against your specific batch's SDS.
- Pre-shipment samples for qualification. New account or new source, your laboratory runs a trial batch before the full quantity ever moves.
- Export machinery handled in-house. Dangerous-goods classification, cylinder/ISO-tank logistics, packing, labelling, freight booking and customs paperwork are ours to manage.

Check the batch SDS — this compound is an extremely flammable gas
Ethylamine is classified under GHS as an extremely flammable gas, causes serious eye irritation and may cause respiratory irritation. The safety data sheet supplied with your consignment is the authority that should govern your risk assessment, PPE selection, exposure monitoring and emergency planning — not any general statement on this page.
Classified hazards (treat conservatively)
H220Extremely flammable gas.H319Causes serious eye irritation.H335May cause respiratory irritation.
Classification reflects published GHS data for this CAS number, including extreme flammability alongside eye and respiratory irritation; treat any release, including from aqueous solution, with correspondingly careful ignition-source and ventilation controls until your batch SDS confirms the classification that applies. Always read the SDS issued with your specific batch before finalising your handling procedure.
Spill & emergency orientation
Plan your response before the container arrives, not after a spill occurs. 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.
- Eliminate all ignition sources immediately given the extremely-flammable-gas classification — this is the first priority in any release response.
- Evacuate and ventilate the area, and shut off the source of release if it is safe to do so.
- Chemical-protective clothing and respiratory protection are required for release response — this is not a task for standard PPE.
- Contain aqueous-solution spills, do not hose to drain — neutralise cautiously under trained supervision.
- Have the SDS with the casualty at all times so the treating clinician has the product identity, CAS number and hazard classification in hand.
Storage
- Store cylinders and ISO tanks away from all ignition sources and heat, given the extremely-flammable-gas classification.
- Cool, dry, well-ventilated, access-controlled storage for both gas cylinders and aqueous solution.
- Keep containers tightly closed and pressure-rated equipment properly maintained at all times.
- Segregate from oxidisers, strong acids and other incompatible reactive materials.
- Shelf life is typically 12–24 months in sealed original packing under these conditions, depending on pack format.
Handling & PPE
- Eliminate ignition sources at every step, given the flammable-gas classification — use only non-sparking, explosion-rated equipment nearby.
- Chemical-resistant gloves and eye protection as standard for any manual handling of the aqueous solution.
- Fume hood, engineered local exhaust ventilation or gas-detection systems are required given the respiratory- and eye-irritant classifications.
- Respiratory protection for any operation with a realistic risk of gas release.
- Dispose of waste as regulated hazardous chemical waste via a permitted, flammable-waste-qualified disposal route only.
Transport
We confirm and apply the correct transport classification for every consignment of this compound based on your specific batch's documentation, rather than assuming a fixed classification. We classify each shipment, apply appropriate packaging and labelling, and file the export documentation before booking — ask us for the current paperwork when you plan the shipment.
What travels with every consignment
A chemical shipment is only as good as the file that travels with it. Verifying what the source plant sends is precisely the work you are buying from a supplier.
Certificate of Analysis
Batch-specific assay by GC (gas) or titration (aqueous solution) — 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 and disposal, matched precisely to the batch you receive — issued in the language your destination requires.
Dangerous-goods transport documentation
Correct DG classification, packaging group, packaging and labelling confirmed and filed before the container is booked — critical for this flammable, pressure-vessel commodity.
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.
A key building block for triazine herbicide chemistry
Ethylamine's simple, reactive primary nitrogen is what makes it such an efficient herbicide-synthesis building block. The notes below are general background, not a process disclosure.
Manufacture by oxidative amination of ethanol
Ethylamine is produced industrially by reaction of ethanol with ammonia over a catalyst under oxidative/dehydrogenative conditions, alongside diethylamine and triethylamine as co-products.
Separate by distillation
The mixed ethylamines are separated by fractional distillation, with ethylamine typically isolated as the lowest-boiling fraction.
Condense onto the triazine core
Ethylamine reacts with a chlorotriazine intermediate, displacing chloride and installing the ethylamino substituent that defines herbicides such as atrazine and simazine.
Complete the herbicide synthesis
The resulting mono- or di-substituted triazine is further elaborated (commonly with a second, different alkylamine) to give the finished herbicide active ingredient.
Why concentration and pack format matter
Ethylamine is supplied in several different commercial forms, and getting the wrong one for your process changes handling requirements and downstream chemistry substantially:
- Anhydrous liquefied gas is preferred where the reaction is water-sensitive or where gas-phase dosing equipment is already in place.
- Aqueous solution (commonly 70% w/w) is the standard commercial form for herbicide-manufacture feedstock use, where liquid-handling infrastructure is already in place.
- Co-produced diethylamine and triethylamine carryover from the manufacturing process is the reason assay and amine-distribution testing are standard on every batch.
That is the reason we quote against your written specification rather than a generic grade, and the reason the batch COA is shared for approval before dispatch rather than sent with the invoice.
| Intermediate | Principal outlet |
|---|---|
| Ethylamine CAS 75-04-7 — this product | Triazine herbicide precursor Primary amine |
| Diethylamine CAS 109-89-7 | Co-produced secondary amine See our Diethylamine page |
| Triethylamine CAS 121-44-8 | Co-produced tertiary amine See our Triethylamine page |
If your route calls for one of the others, we supply those as well — see the full intermediate range. Send the CAS number and we will confirm the correct material before quoting.
What actually moves the price of this intermediate
As the feedstock behind atrazine and simazine manufacture, ethylamine's pricing tracks ethanol/ammonia feedstock costs and the seasonal cycle of agrochemical demand.
Upstream feedstock
The route back to this compound runs through ethanol and ammonia. Movements in ethanol and ammonia costs feed through within a quarter or so.
- Ethanol and ammonia costs set the floor
- Catalytic amination adds a real process cost
- We flag feedstock-driven moves in the quote
Purity tier by end use
Herbicide-manufacture routes typically specify a defined assay and amine-distribution limit; rubber and fine-chemical use is generally less exacting. Tell us your actual end use and we will avoid over-specifying.
- Tell us the reaction you are running
- We will say when a looser spec is unnecessary
- Amine-distribution purity matters most on herbicide routes
Order size and pack format
Herbicide manufacturers often move larger tonnage on a seasonal cycle tied to planting season, while smaller buyers order in commercial pack sizes. Tell us your requirement and cycle early.
- Small commercial packs are readily available
- Seasonal bulk orders need advance lead-time planning
- We are candid about what is and isn't quickly available
Broad producer base
Being tied to major global herbicide families, ethylamine has a reasonably deep producer base, though dangerous-goods logistics narrow the practical options for gas-phase supply.
- Multiple qualified sources maintained
- We compare sources on both price and quality
- Second source held in reserve where available
Freight & dangerous-goods considerations
Confirm the correct dangerous-goods classification and pack format (gas cylinder vs. aqueous solution) for your specific need — this materially affects freight cost and available carrier options, and we handle that confirmation as part of every quote.
- Classification confirmed per batch
- We quote FOB, CIF, CFR or DDP as you prefer
- Compare on landed cost, not ex-works
Lead time realism
Pressure-vessel logistics, dangerous-goods documentation and seasonal agrochemical demand can add lead time over a standard commodity chemical — we would rather tell you honestly than promise a turnaround we cannot deliver.
- Ask early for the most accurate lead time
- Sample qualification adds time but reduces risk
- We flag any delay as soon as we know about it
| If your end use is… | Specify |
|---|---|
| Triazine herbicide manufacture | Standard 70% aqueous grade; seasonal bulk volumes |
| Rubber-product manufacturing | Standard technical grade generally sufficient |
| Fine chemical / research synthesis | Confirm downstream reaction tolerance |
| Laboratory / trial | Small pack, fast despatch |

Support that goes beyond shipping the pack
What our technical desk will do
- Confirm which pack format your process needs. We compare liquefied gas and aqueous-solution options against your existing infrastructure before we quote.
- Verify the hazard classification against your specific batch. Given the extreme flammability, we do not rely on a single reference source — we check the SDS for the lot we are quoting.
- Give you honest lead-time guidance for pressure-vessel logistics and seasonal agrochemical demand that may add time over a standard commodity chemical.
- 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
- Import controls vary by destination. We check the destination rules before quoting, not after you have raised the PO.
- 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.
- Transport classification is confirmed for every batch based on its own documentation and filed before booking.
- Downstream regulatory status of whatever you build from this intermediate is a separate question your own regulatory team should confirm for your specific finished product.
None of the above is legal advice — your own regulatory affairs team owns the final compliance position for your import. What we commit to is giving you accurate product identity data, an honest statement of the hazard classification for your specific batch, and complete documentation to work from.
