The present work was effective in combining equimolar 4aminoacetophene with leucine amino acid in the synthesis of a new corrosion inhibitor (S2). 1 H N.M.R., 13 C N.M.R., C.H.N., and FTIR techniques proved its structure. At 298.15 K, 0.5 M hydrochloric acid solution was measured to affect the S2 inhibitor on the CS (X56) electrode. S2 has been verified as a suitable inhibitor and as a mixed interference to control both anodic and the cathodic response to delayed corrosion by blocking the active sites in the surface electrode by the results of electrochemical measurements as open circuit potential and Tafel scan. These observations were accompanied by FE-SEM images and mapping spectrums that showed a transparent surface protective layer.
