Used as a corrosion inhibitor in industrial cooling systems and metalworking fluids, protecting copper and its alloys from oxidative degradation. Also serves as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals due to its stable triazole ring. Employed in coordination chemistry as a ligand for transition metal catalysts, enhancing reaction efficiency in cross-coupling reactions. Additionally, found in some photo-stabilized formulations for coatings and polymers, improving resistance to UV degradation.
