Metabolite Identification

Common Name

p-Phenetidine

Description

4-ethoxyaniline, also known as 4-phenetidine or 4-aminophenetole, 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. 4-ethoxyaniline is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on 4-ethoxyaniline. This compound has been identified in human blood as reported by (PMID: 31557052 ). P-phenetidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically p-Phenetidine 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.
