Metabolite Identification
Common Name2-(4-Chlorophenoxy)propionic acid
Description2-(4-chlorophenoxy)propanoic acid, also known as CPP, belongs to the class of organic compounds known as 2-phenoxypropionic acids. These are aromatic compounds hat contain a phenol ether attached to the C2-atom of a phenylpropionic acid. Based on a literature review a small amount of articles have been published on 2-(4-chlorophenoxy)propanoic acid. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-(4-chlorophenoxy)propionic acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-(4-Chlorophenoxy)propionic 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.
