General description

2,2′-Thiodiethanol (TDE), also known as bis(2-hydroxyethyl)sulfide and thiodiglycol, is commonly used as a solvent in organic synthesis. It is a nontoxic, water soluble embedding medium for optical microscopy. It is the hydrolysis product of sulfur mustard.

Application

2,2′-Thiodiethanol can be used:
  • In the synthesis of luminescent polynuclear gold(I) phosphine complexes.
  • To prepare Co(II) and Mn(II) complexes.
  • As a reactant to prepare sulfone-containing polyurethane materials for electrophoretic applications.
