Metabolite Identification
Common Name2-Ethylsulfanyl-1H-benzoimidazole
Description2-(ethylsulfanyl)-1H-1,3-benzodiazole belongs to the class of organic compounds known as benzimidazoles. These are organic compounds containing a benzene ring fused to an imidazole ring (five member ring containing a nitrogen atom, 4 carbon atoms, and two double bonds). Based on a literature review very few articles have been published on 2-(ethylsulfanyl)-1H-1,3-benzodiazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-ethylsulfanyl-1h-benzoimidazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Ethylsulfanyl-1H-benzoimidazole 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.
