Metabolite Identification
Common Name2-Ethylhexyl diphenyl phosphate
Description2-ethylhexyl diphenyl phosphate belongs to the class of organic compounds known as aryl phosphotriesters. These are aryl phosphates in which the phosphate is esterified at exactly three positions. Based on a literature review very few articles have been published on 2-ethylhexyl diphenyl phosphate. This compound has been identified in human blood as reported by (PMID: 31557052 ). 2-ethylhexyl diphenyl phosphate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically 2-Ethylhexyl diphenyl 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.
