Metabolite Identification
Common NameCyclohexylamine
DescriptionCyclohexylamine is a food contaminant arising from its use as a boiler water additive Cyclohexylamine, also called hexahydroaniline, 1-aminocyclohexane, or aminohexahydrobenzene, is an organic chemical, an amine derived from cyclohexane. It is a clear to yellowish liquid with fishy odor, with melting point of 17.7 °C and boiling point 134.5 °C, miscible with water. Like other amines, it is of mildly alkaline nature, compared to strong bases such as NaOH, but it is a stronger base than its aromatic sister compound aniline, which differs only in that its ring is aromatic. It is flammable, with flash point at 28.6 °C. Explosive mixtures with air can be formed above 26 °C. It is toxic by both ingestion and inhalation; the inhalation itself may be fatal. It readily absorbs through skin, which it irritates. It is corrosive. Cyclohexylamine is listed as an extremely hazardous substance as defined by Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act
