The purpose of the study is to synthesize and characterize a new arylazo compound 1,7-bis(2-hydroxyphenyl)-4-(phenylhydrazono)hepta-1,6-diene-3,5-dione (HPHDD) . The corrosion inhibition behavior of the compound on mild steel in 1 M HCl was investigated using weight loss method, electrochemical impedance spectroscopy, and potentiodynamic measurements. The results revealed that this arylazo compound effectively inhibited the corrosion reaction in HCl medium. The surface analysis indicated that this inhibitor was strongly adsorbed on the metal surface. The electrochemical studies at different temperatures showed the thermal stability of the inhibitor. Quantum chemical studies were performed using DFT at the B3LYP/6-31G (d, p)basis set. Contrary to the carcinogenic property of usual anti-corrosive substances, the in vitro cytotoxic studies of the newly synthesized arylazo derivative against Dalton lymphoma ascites cells confirm the anti-tumor properties of the compound.
