| Common Name | 2H-Benzimidazole-2-thione, 1,3-dihydro-4-methyl- |
|---|
| Description | 7-methyl-1H-1,3-benzodiazole-2-thiol 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). 7-methyl-1H-1,3-benzodiazole-2-thiol is a strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). 2h-benzimidazole-2-thione, 1,3-dihydro-4-methyl- is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2H-Benzimidazole-2-thione, 1,3-dihydro-4-methyl- 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. |
