| Common Name | 3-Nitro-1H-pyrazole |
|---|
| Description | 3-Nitro-1H-pyrazole, also known as DJW 94, 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 3-Nitro-1H-pyrazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). 3-nitro-1h-pyrazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 3-Nitro-1H-pyrazole 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. |
