Metabolite Identification
Common Name4-Aminothiophenol
Description4-Aminothiophenol, also known as 6976-04-1 (na salt) or p-mercaptoaniline, belongs to the class of organic compounds known as thiophenols. Thiophenols are compounds containing a thiophenol ring, which a phenol derivative obtained by replacing the oxygen atom from the hydroxyl group (attached to the benzene) by a sulfur atom. Based on a literature review very few articles have been published on 4-Aminothiophenol. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-aminothiophenol is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Aminothiophenol 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.
