Metabolite Identification
Common Name1-O,4-O-Bis[(2S)-2-ethylhexyl] 2-O-[(2R)-2-ethylhexyl] benzene-1,2,4-tricarboxylate
Description1-O,4-O-Bis[(2S)-2-ethylhexyl] 2-O-[(2R)-2-ethylhexyl] benzene-1,2,4-tricarboxylate, also known as tri-(2-ethylhexyl) trimellitate or TOTM, belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Based on a literature review very few articles have been published on 1-O,4-O-Bis[(2S)-2-ethylhexyl] 2-O-[(2R)-2-ethylhexyl] benzene-1,2,4-tricarboxylate. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-o,4-o-bis[(2s)-2-ethylhexyl] 2-o-[(2r)-2-ethylhexyl] benzene-1,2,4-tricarboxylate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-O,4-O-Bis[(2S)-2-ethylhexyl] 2-O-[(2R)-2-ethylhexyl] benzene-1,2,4-tricarboxylate is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
