一般描述

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

应用

应用于一种用途广泛、硫代硫酸盐辅助,合成了多种二胺 CuCN 配合物。[1]
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.
 

特点和优势

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