Octyl acetate, or octyl ethanoate, is an organic compound with the formula CH3(CH2)7O2CCH3. It is classified as an ester that is formed from 1-octanol (octyl alcohol) and acetic acid. It is found in oranges, grapefruits, and other citrus products.[3]

Octyl acetate can be synthesized by a condensation of 1-octanol and acetic acid:

CH3(CH2)7OH + CH3CO2H → CH3(CH2)7O2CCH3 + H2O


Because of its fruity odor, octyl acetate is used as the basis for artificial flavors and in perfumery. It is also as a solvent for nitrocellulose, waxes, oils, and some resins.
