Isopropylamine
A branched primary amine with an outsized footprint in global agriculture: isopropylamine is the counter-ion behind the glyphosate isopropylamine salt, one of the most widely formulated herbicide products in the world, alongside its role in atrazine, imazapyr and a spread of specialty-chemical intermediates.
Chelora Chemicals supplies isopropylamine to agrochemical, coatings and specialty-chemical manufacturers worldwide, with full GHS documentation on every consignment.

What Isopropylamine is used for
Isopropylamine is a colourless, hygroscopic liquid with an ammonia-like odour, boiling just above room temperature and fully miscible with water. It is the branched isomer of the three-carbon amine pair — the amine group sits on the central carbon rather than the end of the chain.
Its single best-known use is forming the isopropylamine salt of glyphosate, the active-ingredient salt behind one of the most widely formulated herbicide products anywhere in the world. Beyond glyphosate, it is used in the synthesis of other major herbicides including atrazine and imazapyr, and serves as a building block across coatings, plastics-processing additives, rubber-chemical, pharmaceutical intermediate and petroleum-industry additive chemistry.
Isopropylamine vs. n-propylamine
- Isopropylamine (this product) branched, amine on the central carbon — the dominant amine in herbicide-salt chemistry.
- n-Propylamine straight-chain, amine on the terminal carbon — more general-purpose. See that page.
See our wider amine range for the other aliphatic amines we supply, including n-butylamine and sec-butylamine.
Appearance and handling character
Isopropylamine is extremely flammable, with a boiling point low enough that it behaves close to a volatile liquid at warm ambient temperatures. It is also hygroscopic and fully water-miscible.

How we supply Isopropylamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. On an amine with a seasonal, agrochemical-weighted demand pattern, that means matching your order to the production calendar it actually needs to serve, not whatever a single plant happens to have on hand.
We place your order with whichever qualified producer best matches your required grade, your price point and your delivery window.
We keep a second qualified source on this line, so a single-plant disruption never becomes your production problem.
- Assay confirmed before we quote. Water content matters to downstream glyphosate-salt and herbicide-synthesis yield.
- Seasonal call-off scheduling. We hold contracted tonnage and release it against your agrochemical production calendar.
- UN classification confirmed. Correctly filed under UN 1221, Class 3, every time.
- Batch traceability to the producing plant. Full chain of custody documentation on request.
- Export machinery handled in-house. Classification, approved packing, labelling, freight booking and customs paperwork are ours to manage.
- Second source held in reserve. A single-plant disruption during peak season never becomes your problem.
Packed the way your plant receives it
Drum, IBC or bulk — tell us your preferred format and we will quote and classify to it.
200 L / 55 USG
Standard UN-approved steel drums for flammable liquids, the usual choice for most orders.

Contracted call-off supply
We hold contracted tonnage and release it against your seasonal production calendar.
Extremely flammable, and irritating to skin and eyes
Isopropylamine's low boiling point makes vapour-ignition control the central handling concern. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H224Extremely flammable liquid and vapour.H315Causes skin irritation.H319Causes serious eye irritation.H335May cause respiratory irritation.
Always read the SDS issued with your specific batch. Handle with chemical-resistant gloves, splash goggles and adequate ventilation, kept well away from ignition sources.
Storage
Store in tightly closed containers in a cool, well-ventilated area away from heat, sparks, open flame and oxidisers. The low boiling point means headspace vapour pressure must be managed even at moderate ambient temperatures.
Handling
Use with local exhaust ventilation. Ground and bond containers during transfer to control static discharge in a flammable-vapour environment. Avoid skin and eye contact.
Transport
Ships as UN 1221, Class 3 (flammable liquid). We confirm and document packing group and exact classification for your specific shipment and destination.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Assay and water content confirmed against your process requirement before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and dangerous-goods paperwork checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How isopropylamine is made
Isopropylamine is produced industrially by the catalytic amination of isopropanol (or acetone) with ammonia over a suitable hydrogenation catalyst. This is a standard, well-established industrial route for branched primary alkylamine production.
We do not publish operating process parameters here; this is background only. Full technical and safety documentation accompanies every shipment, and any process-specific detail you need is best confirmed directly with our technical desk.
