Metabolite Identification
Common NameBis(2-ethylhexyl) phthalate
DescriptionDi(2-ethylhexyl)phthalate, also known as DEHP or di-iso-octyl phthalate, belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. Di(2-ethylhexyl)phthalate is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Di(2-ethylhexyl)phthalate is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Based on a literature review a significant number of articles have been published on Di(2-ethylhexyl)phthalate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Bis(2-ethylhexyl) phthalate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Bis(2-ethylhexyl) phthalate 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.
