Metabolite Identification
Common NameDimethoate
DescriptionDimethoate, also known as phosphamide or dimethoic acid, belongs to the class of organic compounds known as dithiophosphate o-esters. These are o-ester derivatives of dithiophosphates, with the general structure RSP(O)(O)=S (R = organyl group). Based on a literature review a significant number of articles have been published on Dimethoate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Dimethoate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Dimethoate 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.
