Metabolite Identification
Common NameN-Hydroxyphenetidine
DescriptionN-Hydroxyphenetidine belongs to the class of organic compounds known as phenol ethers. These are aromatic compounds containing an ether group substituted with a benzene ring. Based on a literature review a significant number of articles have been published on N-Hydroxyphenetidine. This compound has been identified in human blood as reported by (PMID: 31557052 ). N-hydroxyphenetidine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically N-Hydroxyphenetidine 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.
