Description

Redox indicatorSodium 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-(aninile-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 nano crystals by reaction with chloroauric acid in the presence of polyethylene glycol.
