Metabolite Identification
Common Name3,4-Dimethylbenzoic acid
Description3,4-Dimethylbenzoic acid 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. 3,4-Dimethylbenzoic acid has been detected, but not quantified in, several different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), domestic pigs (Sus scrofa domestica), and herbs and spices. This could make 3,4-dimethylbenzoic acid a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 3,4-Dimethylbenzoic acid.
