Used as a corrosion inhibitor in cooling systems and metalworking fluids, particularly for copper and its alloys. It forms a protective film on metal surfaces, preventing oxidation and degradation in aqueous environments. Also employed in coatings and lubricants to enhance long-term stability and performance. Shows effectiveness in mixed-metal systems due to its ability to chelate metal ions. Additionally, utilized in some polymer formulations as a stabilizer against environmental degradation.
