Common Name | 2-Methylbenzoic acid |
---|
Description | 2-Methylbenzoic acid, also known as 2-toluic acid or O-methylbenzoate, belongs to the class of organic compounds known as benzoic acids. These are organic Compounds containing a benzene ring which bears at least one carboxyl group. 2-Methylbenzoic acid has been detected, but not quantified in, milk (cow). This could make 2-methylbenzoic acid a potential biomarker for the consumption of these foods. 2-Methylbenzoic acid 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 significant number of articles have been published on 2-Methylbenzoic acid. |
