sec-Butylamine

sec-Butylamine is an organic chemical compound, specifically a secondary amine, with the formula CH3CH2CH(NH2)CH3. sec-Butylamine belongs to the class of organic compounds known as monoalkylamines. Together with n-butylamine, tert-butylamine, and isobutylamine, sec-butylamine is one of the isomeric amines of butane. The amine function on position two makes sec-butylamine a chiral compound and therefore exists as two enantiomers. sec-Butylamine is a weak basic compound (based on its pKa). It is a colorless to yellow clear liquid, with a strong fishy-ammonia odor. Sec-Butylamine has been used to control fungal infection in crops (PMID: 5464092) and is also industrially used in the production of some pesticides. sec-Butylamine is also an amine that has been detected in cannabis plants (PMID: 6991645).
