In general, the diminish of corrosion is controlled by different techniques. Typically, the applied corrosion inhibitor was proved to be a simple and inexpensive technique for corrosion prevention and protection in a corrosive environment. Herein we synthesized a new corrosion inhibitor namely “Benzyl 2-(1-(5-methyl-1-(p-tolyl)-1H-1,2,3-triazole-4-yl)-ethylidene) hydrazine-1-carbodithioate” (BTC). The chemical structure of the tested inhibitor has been elucidating by FT-IR and NMR spectroscopically methods and the number of carbons hydrogen and nitrogen atoms for chemical formula was detected through using CHN analysis. BTC was investigated as a novel inhibitor for mild steel (MS) in an HCl environment, and the inhibition efficiency has been tested gravimetric technique. The results showed that the corrosion rate (CR) and inhibition efficiency (IE%) are in an inverse relationship with each other, as the IE increases with increasing the inhibitor concentration while the CR decreases with increasing concentration. The inhibition efficiency was up to 93.4% at 303.0K in presence of BTC (0.5 mM). The IE decreases with increasing temperature especially at 333 K. The adsorption of BTC on the MS surface was obeyed the adsorption of Langmuir isotherm. In a parallel study, the BTC was examined as an antibacterial compound for Escherichia coli and Staphylococcus aureus. The results showed that the new substance has the significant potential to inhibit the growth of bacterial.
