Metabolite Identification
Common Name2,4,5-Triphenylimidazole
Description2,4,5-Triphenylimidazole, also known as lophine, belongs to the class of organic compounds known as phenylimidazoles. These are polycyclic aromatic compounds containing a benzene ring linked to an imidazole ring through a CC or CN bond. Based on a literature review very few articles have been published on 2,4,5-Triphenylimidazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2,4,5-triphenylimidazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2,4,5-Triphenylimidazole 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.
