    CAS No.: 298-06-6 Formula: C4H11O2PS2 Molecular Weight: 186.23300

    Description

    Diethyl dithiophosphoric acid, sometimes mistakenly called diethyl dithiophosphate, is the organophosphorus compound with the formula (C2H5O)2PS2H. It is the processor for production of the organophosphate insecticide Terbufos. Although samples can appear dark, it is a colorless liquid.
    It is prepared by treating phosphorus pentasulfide with ethanol:
    P2S5 + 4 C2H5OH → 2 (C2H5O)2PS2H + H2S
