Metabolite Identification
Common NameNitrefazole
DescriptionNitrefazole, also known as altimol, belongs to the class of organic compounds known as phenylimidazoles. These are polycyclic aromatic compounds containing a benzene ring linked to an imidazole ring through a CC or CN bond. Nitrefazole is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Nitrefazole is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Nitrefazole 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.
