Application

Thiolactic acid (TLA) can be used as a building block in the synthesis of:
  • Thiolactomycin via oxathiolanone intermediate.
  • 4-Thiazolidinones by reacting various Schiff bases with thioglycolic acid.
  • 1,4-Naphthoquinone derivatives containing sulfur atom for antibacterial and antiviral activity studies.

It can also be used as a bidental chelating agent for the surface modification of titanium dioxide (TiO2) nanoparticles for the removal of cadmium from waste water.

The toxicity of CdTe QDs modified with three different ligands, namely mercaptopropionic acid (MPA), N-acetyl-L-cysteine (NAC), and glutathione (GSH), were investigated via microcalorimetric, spectroscopic, and microscopic methods. The three ligand-modified QDs have nearly identical hydrodynamic size. The results of the
