sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH3CH2CH(NH2)CH3, and occurs as a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine and isobutylamine. It is very harmful to aquatic organisms.
sec-Butylamine is used as a fungicide[3] and is considered a high production volume chemical. It is undergoing comprehensive review by the American Chemistry Council's Amines Panel as part of the Primary Amines Category.[citation needed]
Chemical structure
sec-Butylamine is one of the isomers of butylamine. It is chiral and therefore can exist in either of two enantiomeric forms.
