Metabolite Identification
Common NameIsopropyl benzoate
DescriptionIsopropyl benzoate belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Isopropyl benzoate is a sweet, balsamic, and floral tasting compound. Isopropyl benzoate has been detected, but not quantified in, several different foods, such as cocoa and cocoa products, cocoa beans (Theobroma cacao), fruits, and pomes. This could make isopropyl benzoate a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Isopropyl benzoate.
