Metabolite Identification
Common NameO-Anisidine
Descriptiono-anisidine, also known as 2-aminoanisole or 2-methoxyaniline, belongs to the class of organic compounds known as aminophenyl ethers. These are aromatic compounds that contain a phenol ether, which carries an amine group on the benzene ring. Based on a literature review a significant number of articles have been published on o-anisidine. This compound has been identified in human blood as reported by (PMID: 31557052 ). O-anisidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically O-Anisidine 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.
