Metabolite Identification
Common NameClofibric acid
Descriptionclofibric acid, also known as 4-CPIB or chlorfibrinate, belongs to the class of organic compounds known as phenoxyacetic acid derivatives. Phenoxyacetic acid derivatives are compounds containing an anisole where the methane group is linked to an acetic acid or a derivative. clofibric acid is an extremely weak basic (essentially neutral) compound (based on its pKa). This compound has been identified in human blood as reported by (PMID: 31557052 ). Clofibric acid is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Clofibric 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.
