General description

Sodium diphenylamine-4-sulfonate has the ability to form colored complexes with metal ions. Hence it is commonly used as an indicator to estimate the concentration of metal ions. It is also an efficient quencher of electrochemiluminescence of tris (2, 2′-bipyridine)-ruthenium (II).

Application

Sodium diphenylamine-4-sulfonate may be used in the synthesis of poly-(aniline-co-N-(4-sulfophenyl)aniline via polymerization with aniline. It may also be used as a reductant in the synthesis of branched gold nanocrystals from gold(III) chloride trihydrate in the presence of polyethylene glycol. These nanocrystals have potential application as electrocatalysts.
