Metabolite Identification
Common Name4-(2-Pyridylazo)resorcinol
Description4-(2-Pyridylazo)resorcinol belongs to the class of organic compounds known as resorcinols. Resorcinols are compounds containing a resorcinol moiety, which is a benzene ring bearing two hydroxyl groups at positions 1 and 3. Based on a literature review very few articles have been published on 4-(2-Pyridylazo)resorcinol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-(2-pyridylazo)resorcinol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-(2-Pyridylazo)resorcinol 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.
