Description

Cyclohexylamine (CAS 108-91-8 ), commonly abbreviated as CHA, is a primary aliphatic amine used across industrial and specialty chemical manufacturing. It functions as a corrosion inhibitor, pH buffer, and reactive intermediate. In boiler water and steam condensate systems, CHA neutralizes acidic condensate and forms a protective film on metal surfaces. This reduces corrosion-related downtime in industrial utilities and steam distribution networks. Rubber and tire manufacturers use it as a precursor to sulfenamide accelerators, which control vulcanization rates. These accelerators are essential for tire compounds and various industrial rubber goods production. In agrochemical production, CHA serves as a building block for herbicide and pesticide active ingredients. This includes cyclohexylamine salt formulations of glyphosate used in modern agricultural applications. Pharmaceutical manufacturers rely on it as an intermediate in the synthesis of active pharmaceutical ingredients. It is also frequently utilized as a counterion in drug salt formation processes. Cyclohexylamine is supplied as a colorless to pale yellow liquid in standard bulk and intermediate packaging. Options include drums and ISO tank containers to suit different logistics and storage needs. Technical grade and high-purity grades are available, with specifications aligned to industrial synthesis requirements. Buyers sourcing for regulated applications typically require documentation such as GMP compliance. A certificate of analysis with purity confirmation is provided to ensure the material meets strict quality standards. This ensures reliability for both large-scale industrial use and specialized chemical synthesis. Contact us for supply of Cyclohexylamine Request Quote
