Metabolite Identification
Common NameIndazole
DescriptionIndazole, also known as 1,2-diazaindene or 1H-benzopyrazole, belongs to the class of organic compounds known as indazoles. Indazoles are compounds containing an indazole, which is structurally characterized by a pyrazole fused to a benzene. Based on a literature review a significant number of articles have been published on Indazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Indazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Indazole 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.
