The synthesis of CT was accomplished with the help of cinnamaldehyde and thiosemicarbazide using Schiff-base chemistry, and the product's structure was verified by 1 H-NMR and IR spectroscopy. The anti-corrosion performance of CT was performed on the MS using gravimetric methods, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization studies (PDP). The experimental results of the CT molecule's adsorption on an MS surface in 1M and 15% HCl align with the Langmuir adsorption isotherm. The gravimetric analysis confirmed that the developed CT exhibited 95.02% (using 1mM of CT) and 96.65% (using 4mM of CT) corrosion inhibition efficiency (IE) in 1M and 15% aqueous HCl at 303K, respectively. But at 343K, in 1M and 15% HCl, the anti-corrosion performance of CT on MS was reduced to 86.74% and 92.50%, respectively.
