General description

4-Methyl-4H-1,2,4-triazole-3-thiol reacts with ethyl bromoacetate to yield ethyl[(4-methyl-4H-1,2,4-triazol-3-yl)sulfanyl]acetate. Electrochemically anticorrosive behavior of self-assembled monolayers of 4-methyl-4H-1,2,4-triazole-3-thiol on the silver electrode has been studied by electrochemical impedance spectroscopy and polarization measurements.

Application

  • Corrosion study of mild steel in aqueous sulfuric acid solution using 4-methyl-4H-1, 2, 4-Triazole-3-Thiol: Examines the use of 4-Methyl-4H-1,2,4-triazole-3-thiol as a corrosion inhibitor for mild steel in sulfuric acid solutions (MEHMETI and BERISHA, 2017).
  • Dimeric and polymeric mercury (II) complexes containing 4-methyl-1, 2, 4-triazole-3-thiol ligand: Investigates the coordination chemistry of mercury with 4-methyl-4H-1,2,4-triazole-3-thiol, providing insights into its potential applications in materials science (TAHERIHA, GHADERMAZI, and AMANI, 2015).
  • Synthesis, characterization and biological studies of 1, 2, 4-triazole derivatives having piperidine moiety: Focuses on the synthesis and biological evaluation of 1,2,4-triazole derivatives, including those modified with a piperidine group and 4-Methyl-4H-1,2,4-triazole-3-thiol (FAROOQ et al., 2023).
