This chemical is primarily used as a corrosion inhibitor in industrial processes, particularly in metal treatment and cooling water systems. It effectively prevents the degradation of metal surfaces by forming a protective layer, thus extending the lifespan of equipment. Additionally, it is employed in the synthesis of pharmaceuticals and organic compounds, where it acts as a versatile intermediate due to its reactive tetrazole and sulfonic acid groups. Its application in photographic developers is also notable, as it aids in enhancing image quality and stability. Furthermore, it serves as a stabilizer in certain polymer formulations, improving their durability and performance under various conditions.
