Used as a corrosion inhibitor in industrial lubricants and metalworking fluids. It helps protect ferrous metals from degradation caused by moisture and acidic byproducts. Its structure allows effective adsorption onto metal surfaces, forming a protective layer that reduces oxidation and wear. Commonly applied in hydraulic systems and gear oils where long-term stability and metal protection are critical. Also found in some specialty coatings to enhance durability and resistance to environmental stress.
