| Common Name | 2-Methylimidazole |
|---|
| Description | 2-Methylimidazole belongs to the class of organic compounds known as imidazoles. Imidazoles are compounds containing an imidazole ring, which is an aromatic five-member ring with two nitrogen atoms at positions 1 and 3, and three carbon atoms. Based on a literature review very few articles have been published on 2-Methylimidazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-methylimidazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Methylimidazole 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. |
