Application

Thiosalicylic acid can be used as:
  • A nucleophilic trapping agent for the desulfenylation of 3-indolyl sulfides to obtain 3-unsubstituted indoles.
  • A starting material to prepare 2′-mercaptoacetophenone, which is used in the synthesis of thioflavanone by reacting with lithium diisopropylamide and benzaldehyde.
  • A stabilizing agent in the synthesis of metal nanoparticles.

It can also be used to prepare 2-thioxanthone-thioacetic acid bimolecular system, which is used as a photoinitiator for free radical polymerization.
