1-Benzyl-4-phenyl-2, 3-dihydro-1H-1,5-benzodiazepin-2-one (P1) was described as novel potent corrosion inhibitor for mild steel in 1M HCl. The inhibitive characteristic of compound (P1) was studied in detail via gravimetric measurement, electrochemical impedance spectroscopy and potentiodynamic polarization. In addition, a quantum chemical study suggests that the 1-Benzyl-4-phenyl-2, 3-dihydro-1H-1,5-benzodiazepin-2-one (P1) ring involved in this inhibitor is structurally essential for the protection of metal surface.
