Description

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.
