Chemical Information
FooDB NameEthyl 2-methylpropanoate
DescriptionEthyl 2-methylpropanoate, also known as isobutyric acid ethyl ester or ethyl isobutyrate, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Ethyl 2-methylpropanoate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Ethyl 2-methylpropanoate is a sweet, alcoholic, and ethereal tasting compound. Ethyl 2-methylpropanoate has been detected, but not quantified in, several different foods, such as pineapples, citrus, pomes, fruits, and evergreen blackberries. This could make ethyl 2-methylpropanoate a potential biomarker for the consumption of these foods.
