Metabolite Identification
Common Name1-Isopropyl-2-methylbenzene
Description1-Isopropyl-2-methylbenzene belongs to the class of organic compounds known as cumenes. These are aromatic compounds containing a prop-2-ylbenzene moiety. 1-Isopropyl-2-methylbenzene has been detected, but not quantified in, citrus. This could make 1-isopropyl-2-methylbenzene a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 1-Isopropyl-2-methylbenzene.
