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.
What is the REACH and TSCA regulatory status of Cyclohexylamine (CHA, Aminocyclohexane)?
Cyclohexylamine (CHA, Aminocyclohexane) (CAS 108-91-8) 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 203-629-0).
