What is Cyclohexylamine?
Cyclohexylamine (CAS 108-91-8), abbreviated CHA, is a primary aliphatic amine used in industrial and specialty chemical manufacturing.
Where is Cyclohexylamine used?
- Corrosion inhibitor, pH buffer and reactive intermediate
- Boiler water and steam condensate systems: neutralizes acidic condensate and forms a protective film on metal surfaces
- Rubber and tire manufacturing: precursor to sulfenamide accelerators that control vulcanization rates
- Agrochemical production: building block for herbicide and pesticide active ingredients, including cyclohexylamine salt formulations of glyphosate
- Pharmaceutical manufacturing: intermediate in API synthesis and counterion in drug salt formation
- It reduces corrosion-related downtime in industrial utilities and steam distribution networks.
Good to know: Buyers for regulated applications typically require GMP compliance documentation; a certificate of analysis with purity confirmation is provided.
Commercial specifications
- Bulk and intermediate packaging: drums and ISO tank containers
- Technical grade and high-purity grades
- Specifications aligned to industrial synthesis requirements
