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.

Frequently Asked Questions
What is n-butylamine used for?
n-Butylamine (CAS 109-73-9) is a primary-amine chemical intermediate for rubber accelerators, agrochemicals, pharmaceuticals, dyes, emulsifiers and corrosion inhibitors, and it is used as a base and pH adjuster.
Is n-butylamine hazardous?
Yes — it is highly flammable, corrosive and toxic, with a low flash point and strong odor. It requires trained handling, vapor control and compatible materials per the SDS and ships under hazardous-materials rules.
What is the CAS and formula of n-butylamine?
It is CAS 109-73-9 (PubChem CID 8007), molecular formula C4H11N. The CoA documents assay and grade.
How is bulk n-butylamine supplied and quoted?
RawSource supplies it as an anhydrous liquid in bulk with CoA and SDS per lot, under HazMat transport. Pricing is quote-based on grade and volume; submit an RFQ with your target quantity.
What is the REACH and TSCA regulatory status of Butylamine (n-Butylamine)?
Butylamine (n-Butylamine) (CAS 109-73-9) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 203-699-2).
