General description

Triphenylphosphine sulfide (TPPS) forms TPPS·3I2 adduct with I2 molecules.

Application

Triphenylphosphine sulfide was used as internal standard in derivatization method for determination of trace levels of elemental sulphur in gasoline using flame ionization detection. It was also used for extraction of Pd(II) from hydrochloric acid solutions containing small amounts of SCN-.
