Metabolite Identification
Common NameHexamethylphosphoramide
Descriptionhexamethylphosphoric triamide, also known as HMPA or phosphoric acid hexamethyltriamide, belongs to the class of organic compounds known as organic phosphoramides. These are organic compounds containing the phosphoric acid amide functional group. Based on a literature review a significant number of articles have been published on hexamethylphosphoric triamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Hexamethylphosphoramide is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Hexamethylphosphoramide 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.
