General description

Thioacetamide (TAA) is a thiocarbonyl compound commonly used as a corrosion inhibitor. It prevents corrosion by forming a protective layer on metal surfaces. It undergoes deuterium exchange reaction with D2O to afford N-dideuterated thioacetamide. Infrared spectral investigations of thioacetamide and its deuterated derivative (N-dideuterated thioacetamide) have been reported.

Application

Hepatotoxin and carcinogen. An additive in enantioselective reduction of β-keto esters with immobilized baker′s yeast.
It may also be used as a sulfide source to prepare metal sulfides of metal ions like cadmium, nickel, zinc and copper.
Thioacetamide has been used as a source of sulfur required for the synthesis of CdS nanoparticlesand quantum dots.
