Full Description

n-Butylamine (CAS 109-73-9) is a primary aliphatic amine — a clear, flammable, strongly basic liquid with the characteristic amine/ammoniacal odor. It is a high-volume chemical building block: a reactant and intermediate for rubber accelerators, agrochemicals, pharmaceuticals, dyes, emulsifiers and corrosion inhibitors, and a base/pH adjuster. Identity: PubChem.

What is n-butylamine?

n-Butylamine is CH3(CH2)3NH2, a primary amine that is a strong base and a good nucleophile. Those properties make it a versatile reactive intermediate rather than an end-use product. It is volatile, flammable and corrosive, and is handled and shipped accordingly.

Applications by sector

n-Butylamine is almost entirely a chemical intermediate: a feedstock for rubber vulcanization accelerators (thiazoles and sulfenamides), for agrochemicals (herbicides and fungicides), pharmaceuticals, dyes and dye intermediates, emulsifiers and surfactants, and corrosion inhibitors. It is also used as a base and pH adjuster and as an intermediate for N-butyl derivatives. Use is defined by the downstream synthesis; specify grade and purity.

Forms and grades

Supplied as a liquid (anhydrous); confirm assay and grade on the RFQ. The CoA documents the lot. Related amines: dimethylamine, DEAPA.

Handling, hazards and documentation

n-Butylamine is highly flammable, corrosive and toxic, with a low flash point and a strong odor; it requires trained handling, vapor control, compatible materials and grounding per the current Safety Data Sheet (SDS). Each lot ships with a Certificate of Analysis (CoA) and transports under hazardous-materials rules.

Bulk supply and RFQ

RawSource supplies n-butylamine in bulk to chemical-synthesis, rubber, agrochemical and pharmaceutical buyers, with CoA and SDS per lot, under HazMat transport. Submit an RFQ with your grade and target quantity.
