Metabolite Identification
Common Name4-Nitrophenyl butyrate
Descriptionp-nitrophenyl butyrate, also known as PNP-butyrate or PNPB, belongs to the class of organic compounds known as phenol esters. These are aromatic compounds containing a benzene ring substituted by a hydroxyl group and an ester group. Based on a literature review a significant number of articles have been published on p-nitrophenyl butyrate. This compound has been identified in human blood as reported by (PMID: 31557052 ). 4-nitrophenyl butyrate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 4-Nitrophenyl butyrate 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.
