2-butanol acetate, also called sec-butyl acetate, molecular formula CH₃COOCH(CH₃)CH₂CH₃, molecular weight 116.16, is one of the 4 isomers of butyl acetate, which is an achromatic, inflammable and fruit-tasting liquid, and soluble to a variety of resins and organic matters. Its properties resemble other isomers under most circumstances. The biggest difference when it is used as a so ent lies in its lower boiling point than common n-butyl acetates and isobutyl acetates, featuring fast evaporation. Its physical properties are as follows.
