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

Application
Applied in a widely useful, thiosulfate-assisted, synthesis of a variety of diamine-CuCN complexes.[1]
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.

Specification
Sodium thiosulfate is:
 - Stable
 - Environmentally friendly
 - Odorless
 - Inexpensive.
