Metabolite Identification
Common NameMetribuzin
DescriptionMetribuzin belongs to the class of organic compounds known as aryl thioethers. These are organosulfur compounds containing a thioether group that is substituted by an aryl group. Metribuzin is a moderately basic compound (based on its pKa). Metribuzin is a potentially toxic compound. This compound has been identified in human blood as reported by (PMID: 31557052 ). Metribuzin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Metribuzin 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.
