Metabolite Identification

Common Name

4-Chloro-2-methylaniline

Description

4-chloro-2-methylaniline, also known as 4-chloro-O-toluidine or 2-amino-5-chlorotoluene, belongs to the class of organic compounds known as aminotoluenes. These are organic aromatic compounds containing a benzene that carries a single methyl group and one amino group. Based on a literature review very few articles have been published on 4-chloro-2-methylaniline. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-chloro-2-methylaniline is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Chloro-2-methylaniline 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.
