Organic inhibitors are crucial for preserving metals from corrosion in acidic environments. In this regard, the methyl 4-(((1-H benzo[d]imidazol-2-yl)methyl)thio)methyl)benzoate (M-41HBI-2MTMB) was synthesized and investigated as an eco-friendly inhibitor aluminum a molar nitric acid solution (1 M HNO<sub>3</sub>). The gravimetric technique used to study inhibitory properties of molecule, density functional theory (DFT) conducted elucidate inhibition mechanism. experimental data indicated that M-41HBI-2MTMB reduced metal with significant efficiency. increased increase concentration reaching efficiency 98.5% at 5.10<sup>-3</sup> M, temperature 298 K.
