Methyl heptanoate is an organic compound with the chemical formula CH3(CH2)5CO2CH3. It is the methyl ester of heptanoic acid (also known as enanthic acid). This fatty acid ester is a colorless, oily liquid with a fruity, wine-like odor that is used in the flavor and fragrance industries.[1]
Occurrence and production
Methyl heptanoate occurs naturally in trace amounts in some fruits and fermented products. It has been identified as a volatile component in fruits such as strawberries, grapes, and wine and in flowering plants such as Astragalus.[4]
Commercially, it is produced by esterification of heptanoic acid with methanol in the presence of an acid catalyst (typically sulfuric acid) or via transesterification of triglycerides containing heptanoic acid. It is also available through the methanolysis of natural oils that contain other heptanoate esters.[5]
