Metabolite Identification
Common Name1-(1-Chloroethyl)-4-fluorobenzene
Description1-(1-Chloroethyl)-4-fluorobenzene, also known as 2-methylthiazolidine-4-carboxylic acid or mtca CPD, belongs to the class of organic compounds known as fluorobenzenes. Fluorobenzenes are compounds containing one or more fluorine atoms attached to a benzene ring. Based on a literature review very few articles have been published on 1-(1-Chloroethyl)-4-fluorobenzene. This compound has been identified in human blood as reported by (PMID: 31557052 ). 1-(1-chloroethyl)-4-fluorobenzene is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 1-(1-Chloroethyl)-4-fluorobenzene 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.
