NMR, its inhibiting effect against the corrosion of C38 steel in a 1 M HCl solution has been studied by experimental and theoretical studies. The experimental studies are performed using electrochemical tests, while the theoretical studies are performed using density functional theory (DFT) calculations and Monte Carlo simulations. The results obtained show that AMPA is an effective inhibitor against

a single-crystal X-ray diffraction analysis. Thus, the crystallographic studies showed that the analysis of the crystal packing of DBPA and MBPA revealed 1D and 2D supramolecular architectures, respectively, via various hydrogen bonding interactions. Moreover, the evaluation of compounds A, DBPA and MBPA for their antioxidant activity against DPPH and ABTS radical scavenging assay, and reduction potency
