Application

Bis(triphenylphosphoranylidene)ammonium chloride was used in two-phase titration and electrochemistry, done for physiochemical characterization of sildenafil.[1] It was also used in cyclic voltammetry reactions, used to study ion transfer (IT) and electron transfer (ET), at a liquid-liquid interface supported on a metallic electrode.[2]
