Octylamine
A long-chain primary aliphatic amine: octylamine's eight-carbon backbone brings stronger hydrophobic character and lower volatility than its shorter-chain relatives, suiting it to functional fluids, chemical synthesis and laboratory reagent use.
Chelora Chemicals supplies octylamine to specialty chemical, functional-fluid and pharmaceutical-intermediate manufacturers worldwide, with full GHS and UN transport documentation on every consignment.

What Octylamine is used for
Octylamine is a clear to pale yellow liquid with a strong fishy, ammonia-like odour, a straight eight-carbon chain carrying a single primary amine group. Its longer chain than hexylamine or butylamine gives it a higher boiling point, lower volatility and more pronounced hydrophobic character.
Octylamine serves as a precursor for other chemicals, a component in functional fluids, a laboratory reagent, and a reactant in preparing 2H-indazole and 1H-indazolone intermediates used in pharmaceutical research, including compounds studied as MPO (myeloperoxidase) inhibitors.
Where it sits among the alkylamines
- Hexylamine six carbons — balanced reactivity and hydrophobicity. See that page.
- Octylamine (this product) eight carbons — more hydrophobic, lower volatility, functional-fluid applications.
- Cyclohexylamine cyclic C6 amine — different ring-based reactivity profile. See that page.
Appearance and handling character
Octylamine is flammable and corrosive — toxic in contact with skin, causes severe skin burns and eye damage, may cause respiratory irritation, and is very toxic to aquatic life with long-lasting effects — a hazard profile that demands careful containment and personal protection throughout handling.

How we supply Octylamine
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. Octylamine's flammability, corrosivity and UN Class 8 classification mean logistics and documentation matter as much as price — that shapes how we manage this line.
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. Purity matters to downstream synthesis and functional-fluid formulation.
- UN 2735 Class 8 logistics managed end to end. Classification, labelling and carrier compliance confirmed before booking.
- Aquatic-hazard documentation filed correctly. Every shipment carries the correct hazard declarations.
- Scheduled call-off scheduling. We hold contracted tonnage and release it against your consumption calendar.
- 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.

Flammable, corrosive, and very toxic to aquatic life
Octylamine's combination of flammability, corrosivity and aquatic toxicity makes containment and PPE the central handling concerns. The summary below is orientation only — the safety data sheet supplied with your specific batch is the authoritative document.
Classified hazards
H226Flammable liquid and vapour.H301+H311Toxic if swallowed or in contact with skin.H314Causes severe skin burns and eye damage.H332Harmful if inhaled.H335May cause respiratory irritation.H410Very toxic to aquatic life with long-lasting effects.
Always read the SDS issued with your specific batch. Eliminate ignition sources; handle with chemical-resistant gloves, splash goggles, face protection and adequate ventilation; contain spills to prevent waterway contamination.
Storage
Store in tightly closed containers away from heat, sparks and open flame, in a well-ventilated area rated for flammable, corrosive liquids.
Handling
Use with local exhaust ventilation and bond/ground equipment during transfer to control static discharge. Contain any spill and prevent release to drains or watercourses.
Transport
Shipped as UN 2735, Class 8 (Corrosive), Packing Group II. We confirm and document exact classification and packing requirements 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 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 transport paperwork checked by our desk before the shipment is booked.

Each shipment is traceable to its producing batch, with full chain-of-custody records on request.
How octylamine is made
Octylamine is produced industrially by the catalytic amination of 1-octanol with ammonia, or by reductive amination routes, giving the straight-chain primary amine after purification and fractional distillation.
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.
