Metabolite Identification
Common NameEtanidazole
DescriptionEtanidazole, also known as radinyl, belongs to the class of organic compounds known as n-acylethanolamines. N-acylethanolamines are compounds containing an N-acyethanolamine moiety, which is characterized by an acyl group is linked to the nitrogen atom of ethanolamine. Based on a literature review a significant number of articles have been published on Etanidazole. This compound has been identified in human blood as reported by (PMID: 31557052 ). Etanidazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Etanidazole 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.
