<i>sec</i>-Butylamine

sec-Butylamine

Chemical compound

sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH₃CH₂CH(NH₂)CH₃. It is a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine, and isobutylamine. sec-Butylamine is chiral and therefore can exist in either of two enantiomeric forms.
