Application:	Applied in a widely useful, thiosulfate-assisted, synthesis of a variety of diamine-CuCN complexes.
Application:	Sodium thiosulfate can be used as a • Component in the synthesis of unsymmetrical aryl sulfides under aqueous conditions, where C–S–C bond formed in presence of other two components (alcohols and organohalides). • Reagent for the activation of carbon material. • Reagent in the synthesis of S-glycosyl thiosulfates (glycosyl bunte salts) by direct condensation of unprotected sugars using dehydrating agent DMC (2-chloro-1,3-dimethylimidazolinium chloride) in water-acetonitrile solvent mixture. • Reagent with alkyl halide in the synthesis of Bunte salts by SN₂ mechanism using Cu catalyst. • Reagent in the synthesis of aryl thiols from aryl halides by palladium catalyzed cross-coupling reaction.
Features and Benefits:	Sodium thiosulfate is: • Stable • Environmentally friendly • Odorless • Inexpensive.
General description:	Sodium thiosulfate is an inorganic salt composed of thiosulfate and sodium ion with the chemical formula Na₂S₂O₃. It is general reducing agent and useful sulfur source in synthetic chemistry
