Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling water circuits. It protects metal surfaces such as copper and steel by forming a protective film that prevents oxidation and scale buildup. Also employed as a stabilizer in polymer systems due to its ability to chelate metal ions that can catalyze degradation. Its triazole structure enhances thermal stability and compatibility with various formulations, making it suitable for use in coatings and adhesives where long-term durability is required.
