Metabolite Identification
Common Name(4-Aminophenyl)phosphonic acid
Description(4-Aminophenyl)phosphonic acid, also known as phosphanilic acid or potassium phosphanilate, belongs to the class of organic compounds known as aniline and substituted anilines. These are organic compounds containing an aminobenzene moiety. Based on a literature review a significant number of articles have been published on (4-Aminophenyl)phosphonic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). (4-aminophenyl)phosphonic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (4-Aminophenyl)phosphonic acid 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.
