Common Namepyrazole
DescriptionPyrazole, also known as 1,2-diazole or 1H-pyrazol, belongs to the class of organic compounds known as pyrazoles. Pyrazoles are compounds containing a pyrazole ring, which is a five-member aromatic ring with two nitrogen atoms (at positions 1 and 2) and three carbon atoms. Pyrazole exists in all living organisms, ranging from bacteria to humans. Based on a literature review a significant number of articles have been published on Pyrazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Pyrazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 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.
