Product Description:

Redox indicator Sodium diphenylamine-4-sulfonate is used as a pH independent redox indicator used in the determination of redox potential. It is used in the preparation of poly-(aniline-co-N-(4-sulfophenyl)aniline) by polymerization with aniline. It acts as a ligand and form complexes with metal halides like lanthanum(III) chloride. It is also involved in the synthesis of gold nanocrystals by reaction with chloroauric acid in the presence of polyethylene glycol.

Applications:

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.
