General description

3-Amino-1,2,4-triazole-5-thiol inhibits corrosion of copper in aerated acidic chloride pickling solutions[1].

Application

3-Amino-1,2,4-triazole-5-thiol was used to study the inhibition of corrosion of iron in 3.5% NaCl solutions by low concentrations of ATT and 1,1′-thiocarbonyldiimidazole[2]. It was used to prepare surface-enhanced Raman scattering based pH nano- and microsensor using silver nanoparticles[3].
