Application

Applied in a widely useful, thiosulfate-assisted, synthesis of a variety of diamine-CuCN complexes.
Sodium thiosulfate pentahydrate can be used as a sulfur source to synthesize:

Thioester derivatives via one-pot two-step reactions with organic halides and aryl anhydrides.
Sulfur nanoparticles using F. benghalensis leaf extract which acts as a reducing and capping agent.
Unsymmetrical heteroaryl thioethers via multicomponent reaction with heteroaryl chlorides and alcohols.
It can also be used in the fabrication of microencapsulated phase change materials for thermal energy storage applications.

Features

Na2S2O3 5H2O is a low toxic and odorless reagent that can be easily used in large-scale operations.
