Description

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.
