Frequently Asked Questions

What is cyclohexylamine?

Cyclohexylamine (C6H11NH2, CAS 108-91-8) is a cyclic primary amine supplied as a colorless liquid. It is widely used as a neutralizing amine and corrosion inhibitor in boiler feed water, as a rubber vulcanization accelerator, and as a synthesis intermediate for insecticides, plasticizers, and dyestuffs.

Is cyclohexylamine a secondary amine?

No. Cyclohexylamine is a primary amine: a single cyclohexyl group is bonded to an -NH2 group, leaving two N-H bonds. A secondary amine would have two carbon substituents on the nitrogen. This primary-amine basicity is what makes it useful as a neutralizing/corrosion-inhibiting amine in steam and condensate systems.

What is cyclohexylamine used for?

Documented industrial uses include boiler water treatment (neutralizing amine and corrosion inhibitor in steam/condensate systems), rubber chemistry (accelerator and intermediate in vulcanization), synthesis of insecticides, plasticizers, and dyestuffs, and as a component of acid-gas absorbent formulations.

How is cyclohexylamine shipped, and what is its UN number?

Cyclohexylamine is assigned UN 2357 (CYCLOHEXYLAMINE) for transport and is classified under HS code 2921.30. As a regulated material it ships per applicable DOT requirements; the product SDS supplied by RawSource details classification, packaging, and handling. Confirm packaging and lot size when requesting a quote.

What is the cost of bulk cyclohexylamine?

Bulk pricing depends on packaging (drums/totes/IBCs), order volume, and ship-to location, so it is quoted per order rather than listed. Submit a bulk RFQ with your quantity and RawSource will return current pricing with CoA and SDS.
