Chemical Taxonomy
Description belongs to the class of organic compounds known as organothiophosphorus compounds. These are organic derivatives of thiophosphonic acid, thiophosphoric acid, dithiophosphoric acid, or phosphorotrithioic acid, or derivatives thereof. Thiophosphonic acid, dithiophosphoric acid, thiophosphoric acid, and phosphorotrithioic acid are thiophosphorus compounds with the formula OP(O)(=S), OP(S)(=S)O, OP(O)(=S)O, and OP(=S)(S)S, respectively.
