Metabolite Identification
Common NameIsopropyl 2-methylpropanoate
DescriptionIsopropyl 2-methylpropanoate 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). Isopropyl 2-methylpropanoate is a sweet, citrus, and fruity tasting compound. Isopropyl 2-methylpropanoate has been detected, but not quantified in, pineapples (Ananas comosus). This could make isopropyl 2-methylpropanoate a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on Isopropyl 2-methylpropanoate.
