Metabolite Identification
Common NameTributyl Phosphate
Descriptiontributyl phosphate, also known as TBP or butyl phosphoric acid, belongs to the class of organic compounds known as trialkyl phosphates. These are organic compounds containing a phosphate group that is linked to exactly three alkyl chains. Based on a literature review very few articles have been published on tributyl phosphate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tributyl phosphate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tributyl Phosphate 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.
