Metabolite Identification
Common NameClopidol
DescriptionClopidol, also known as meticlorpindol, belongs to the class of organic compounds known as polyhalopyridines. These are organic compounds containing a pyridine ring substituted at two or more positions by a halogen atom. Clopidol is a drug. Based on a literature review a significant number of articles have been published on Clopidol. This compound has been identified in human blood as reported by (PMID: 31557052 ). Clopidol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Clopidol 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.
