Metabolite Identification
Common NameNiridazole
DescriptionNiridazole belongs to the class of organic compounds known as nitrothiazoles. Nitrothiazoles are compounds containing a thiazole ring which bears a nitro group. Based on a literature review very few articles have been published on Niridazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Niridazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Niridazole 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.
