Metabolite Identification
Common Name2-Phenylethyl 2-methylpropanoate
Description2-Phenylethyl 2-methylpropanoate, also known as b-phenylethyl isobutyric acid or benzylcarbinol isobutyrate, belongs to the class of organic compounds known as benzene and substituted derivatives. These are aromatic compounds containing one monocyclic ring system consisting of benzene. 2-Phenylethyl 2-methylpropanoate is a floral, fruity, and pastry tasting compound. 2-Phenylethyl 2-methylpropanoate has been detected, but not quantified in, several different foods, such as alcoholic beverages, beverages, fruits, and herbs and spices. This could make 2-phenylethyl 2-methylpropanoate a potential biomarker for the consumption of these foods. 2-Phenylethyl 2-methylpropanoate is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on 2-Phenylethyl 2-methylpropanoate.
