Ammonium diethyl dithiophosphate or more systematically ammonium ''O'',''O''′-diethyl dithiophosphate, is the ammonium salt of
diethyl dithiophosphoric acid
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 sampl ...
. It is used as a source of the
(C2H5O)2PS2− ligand in coordination chemistry and in analytical chemistry for determination of various ions. It can be obtained by the reaction of
phosphorus pentasulfide
Phosphorus pentasulfide is the inorganic compound with the formula (monomer) or (dimer). This yellow solid is the one of two phosphorus sulfides of commercial value. Samples often appear greenish-gray due to impurities. It is soluble in carbon d ...
