Metabolite Identification
Common NameN-Hydroxy-N'-(4-butyl-2-methylphenyl)formamidine
DescriptionN-Hydroxy-N'-(4-butyl-2-methylphenyl)formamidine belongs to the class of organic compounds known as toluenes. Toluenes are compounds containing a benzene ring which bears a methane group. Based on a literature review very few articles have been published on N-Hydroxy-N'-(4-butyl-2-methylphenyl)formamidine. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-hydroxy-n'-(4-butyl-2-methylphenyl)formamidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Hydroxy-N'-(4-butyl-2-methylphenyl)formamidine 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.
