1-Propylamine

1-Propylamine, also known as 1-aminopropane or propylamine, belongs to the class of organic compounds known as monoalkylamines. These are organic compounds containing a primary aliphatic amine group. 1-Propylamine is a weak base and a colorless volatile liquid with an ammoniacal taste. 1-Propylamine is found in higher concentrations in yellow bell peppers, red bell peppers, and pepper (Capsicum annuum) and in lower concentrations in orange bell peppers and green bell peppers. 1-Propylamine has also been detected in common grapes and wild celeries. This could make 1-propylamine a potential biomarker for the consumption of these foods. Propyl amine hydrochloride can be prepared by reacting 1-propanol with ammonium chloride at high temperature and pressure using a Lewis acid catalyst such as ferric chloride. Propylamine is also found in cannabis plants (PMID: 6991645).
