Metabolite Identification
Common NameDimethylthiophosphate
DescriptionDimethylthiophosphate, also known as O,O-dimethyl phosphorothionate or O,O-dimethylthiophosphoric acid, is classified as a member of the thiophosphoric acid esters. Thiophosphoric acid esters are organic compounds containing the thiophosphoric acid functional group or a derivative thereof, with the general structure ROP(OR')(OR'')=S, where at least one R-group is an organyl group. Dimethylthiophosphate is considered to be slightly soluble (in water) and acidic. (ChemoSummarizer)
