Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
