Application

Thioglycolic acid (TGA) can be used as:
  • A sulfur source and stabilizing agent to synthesize nanocrystalline metal sulfides via hydrothermal reaction. TGA also controls the morphology and particle sizes of nanocrystalline metal sulfides during the process.
  • An effective agglomeration suppressant for the agglomeration of sulfurized mineral pyrite.
  • A reactant to prepare 2,3-disubstituted-thiazolidin-4-one derivatives by one-pot cyclo-condensation reaction with various aldehydes and amines using supported protic acid catalyst.
  • A capping or stabilizing agent to synthesize CdTe quantum dots with controllable photoluminescence wavelengths.
