Abstract
The inhibition effect of three aryl pyrazole pyridine derivatives, namely, 3-methyl-6-oxo-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]pyridine-5-carbonitrile (APP I), 3-methyl-6-oxo-4-(3-phenoxyphenyl)-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]pyridine-5-carbonitrile (APP II) and 3-methyl-6-oxo-4-(thiophen-2-yl)-4,5,6,7-tetrahydro-2H-pyrazolo[3,4-b]pyridine-5-carbonitrile (APP III), against the corrosion of copper in 0.5 M HCl solution has been systematically investigated by electrochemical impedance spectroscopy, potentiodynamic polarization measurements and quant
