Dimethyl dithiophosphoric acid is the organophosphorus compound with the formula (CH3O)2PS2H. It is the processor for production of the organothiophosphate insecticide Malathion. Although samples can appear dark, the compound is a colorless, distillable liquid.[1]

It is prepared by treating phosphorus pentasulfide with methanol:[2]

P2S5 + 4 CH3OH → 2 (CH3O)2PS2H + H2S
