Dicyclohexylamine (CAS 101-83-7) is a secondary amine supplied as a colorless liquid with a strong amine odor, valued as an organic base with excellent oil solubility and as an intermediate for corrosion inhibitors, rubber accelerators and agricultural actives. Our 99% Pure Grade ensures maximum efficiency in complex organic syntheses.
This colorless to yellowish liquid possesses a strong amine odor and acts as a powerful organic base for neutralizing acidic components. It is particularly valued for its excellent oil solubility, making it ideal for formulating lubricant additives and metalworking fluids.
DCHA is also utilized in the synthesis of Vapor Phase Inhibitors (VPI), which provide long-term protection for metal parts during storage. Its chemical structure allows for the creation of stable dicyclohexylammonium salts used in various industrial specialties.
