Used as a corrosion inhibitor in industrial lubricants and metalworking fluids, protecting copper and other non-ferrous metals from oxidation and degradation. Also serves as a stabilizer in polymers and organic materials by scavenging free radicals and preventing UV-induced breakdown. Employed in the synthesis of pharmaceuticals and agrochemicals as a building block due to its stable heterocyclic structure. Additionally, applied in coatings and adhesives to enhance durability and resistance to environmental stress.
