Beschreibung

Anwendung

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.
