<P><B>Abstract</B></P> <P>The corrosion inhibitive property of analgin on mild steel in 1 M HCl was determined for the first time by using experimental and theoretical studies. Weight loss results showed that analgin showed 96.1% inhibition efficiency at 4000 ppm and 298 K. Results showed that analgin acts as a mixed type inhibitor. Effect of concentration of inhibitor and temperature on corrosion inhibition efficiency has been studied. Effect of kinetic and thermodynamic parameters has also been reported. Results show that adsorption of analgin on metal surface follows Langmuir adsorption isotherm. A detailed theoretical data was obtained from Molecular dynamic simulations and quantum chemical calculations using density functional theory (DFT). All the combined results showed appreciable inhibition efficiencies. The morphological and topographical studies were done by SEM and AFM techniques. All the results were in good agreement with each other.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Corrosion protection properties of analgin have been investigated. </LI> <LI> Potentiodynamic polarization curves reveal that tested inhibitor act as mixed type. </LI> <LI> The adsorption of inhibitor obeys Langmuir adsorption isotherm. </LI> <LI> Surface morphology was examined by SEM and AFM. </LI> <LI> The experimental results were correlated with quantum chemical and molecular dynamic stimulation results. </LI> </UL> </P>
