| Description | 4-Methylbenzoic acid, also known as p-toluate or toluenecarboxylate, 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. 4-Methylbenzoic acid exists in all living organisms, ranging from bacteria to humans. 4-Methylbenzoic acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. p-Toluic acid is found in Aloe africana, Artemisia afra and Homo sapiens. p-Toluic acid was first documented in 2002 (PMID: 11876420). Based on a literature review very few articles have been published on 4-Methylbenzoic acid (PMID: 21978560). |
