| Description | 1-Isopropyl-3-methylbenzene, also known as 1-methyl-3-isopropylbenzene, belongs to the class of organic compounds known as cumenes. These are aromatic compounds containing a prop-2-ylbenzene moiety. 1-Isopropyl-3-methylbenzene is found, on average, in the highest concentration within sweet basils (Ocimum basilicum) and blackcurrants (Ribes nigrum). 1-Isopropyl-3-methylbenzene has also been detected, but not quantified in, fruits. This could make 1-isopropyl-3-methylbenzene a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 1-Isopropyl-3-methylbenzene. |
