Metabolite Identification
Common Name2-Methylpropyl acetate
Description2-Methylpropyl acetate, also known as isobutyl acetate or acetate d'isobutyle, 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). The acetate ester of isobutanol. 2-Methylpropyl acetate is an extremely weak basic (essentially neutral) compound (based on its pKa). 2-Methylpropyl acetate is a sweet, apple, and banana tasting compound. Outside of the human body, 2-Methylpropyl acetate has been detected, but not quantified in, several different foods, such as rosemaries, figs, pineapples, cocoa beans, and asian pears. This could make 2-methylpropyl acetate a potential biomarker for the consumption of these foods.
