Metabolite Identification
Common Name5-Methylurapidil
Description5-Methylurapidil belongs to the class of organic compounds known as phenylpiperazines. Phenylpiperazines are compounds containing a phenylpiperazine skeleton, which consists of a piperazine bound to a phenyl group. Based on a literature review a significant number of articles have been published on 5-Methylurapidil. This compound has been identified in human blood as reported by (PMID: 31557052 ). 5-methylurapidil is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 5-Methylurapidil 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.
