A newly synthesized (carbamothiol) oxalamide derivative N1, N2-bis (2-(((2-((2 aminoethyl) amino) ethyl) amino) ethanethioyl) oxalamide (bis N), was investigated for its ability to suppress corrosion of copper in 3.5% NaCl. The chemical structure was demonstrated using FT-IR, 1H-NMR, and 13C-NMR. According to weight loss (WL), potentiodynamic polarization (PDF), and electrochemical impedance spect...
