| 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-thiazol • A capping or stabilizing agent to synthesize CdTe quantum dots with controllable photoluminescence wavelengths. |
