Metabolite Identification
Common NameImazodan
DescriptionIMAZODAN 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. IMAZODAN is a very strong basic compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Imazodan is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Imazodan 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.
