| Common Name | 2-(2-Nitroimidazol-1-yl)-N-(2,2,3,3,3-pentafluoropropyl)acetamide |
|---|
| Description | 2-(2-Nitroimidazol-1-yl)-N-(2,2,3,3,3-pentafluoropropyl)acetamide, also known as 2-nitroimidazole EF5 or EF5 compound, belongs to the class of organic compounds known as nitroaromatic compounds. These are c-nitro compounds where the nitro group is C-substituted with an aromatic group. Based on a literature review very few articles have been published on 2-(2-Nitroimidazol-1-yl)-N-(2,2,3,3,3-pentafluoropropyl)acetamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-(2-nitroimidazol-1-yl)-n-(2,2,3,3,3-pentafluoropropyl)acetamide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-(2-Nitroimidazol-1-yl)-N-(2,2,3,3,3-pentafluoropropyl)acetamide 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. |
