일반 설명

Sodium thiosulfate pentahydrate is a hydrated form of sodium thiosulfate. It is used as a sulfur source for the preparation of various organosulfur compounds.

애플리케이션

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.

특징 및 장점

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