The inhibitive impact of new environmentally friendly synthesized allyl rhodanine azodye derivatives (1-3) versus C-steel and its performance were detected in 2 malar hydrochloric acid solution utilized mass reduction, Tafel polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation (EFM) techniques. The inhibition efficiency percentage (% IE) of these investigated composite is: inhibitor (1) > (2) > (3). The mixed-kind inhibitor allyl rhodanine azodye compounds have isotherm Temkin-following adsorption habits on C-steel. The temperature effect on corrosion protection has been research and the activation thermodynamic was measured. It appears that a decrease in corrosion protection effectiveness with rising temperatures caused the inhibitor to desorb. Utilizing scanning electron microscope and energy dispersive X-ray spectroscopy (SEM–EDX) and the morphology of inhibited C-steel was examined. The data show that the effectiveness of the protection increases with increasing inhibitor doses. The receptor of the breast cancer 3hb5-oxidoreductase was predicted to bind with allyl rhodanine azodye derivatives via molecular docking. The data showing a decline in EHOMO and ELUMO orders corresponds with an increase in % IE that strengthens the preceding order.
