Used as a corrosion inhibitor in industrial cooling systems and metalworking fluids, particularly effective in protecting copper and its alloys from oxidation and pitting. It functions by forming a protective film on metal surfaces, preventing the interaction of corrosive agents such as oxygen and chlorides. Commonly applied in water treatment, automotive antifreeze formulations, and hydraulic systems. Also utilized in some electronic applications to protect copper wiring and components during manufacturing and operation. Shows good thermal stability and compatibility with other additives in formulated fluids.
