Metabolite Identification
Common NameEthyl 2-methylpropanoate
DescriptionEthyl 2-methylpropanoate, also known as ethyl 2,2-dimethylacetate or isobutyric acid ethyl ester, 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). A fatty acid methyl ester obtained by the formal condensation of isobutyric acid with ethanol. 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. Outside of the human body, Ethyl 2-methylpropanoate has been detected, but not quantified in, several different foods, such as apples, figs, pomes, fruits, and lowbush blueberries. This could make ethyl 2-methylpropanoate a potential biomarker for the consumption of these foods.
