Metabolite Identification
Common NameMetoprine
DescriptionMetoprine belongs to the class of organic compounds known as dichlorobenzenes. Dichlorobenzenes are compounds containing a benzene with exactly two chlorine atoms attached to it. Metoprine is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Metoprine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Metoprine 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.
