Used as a corrosion inhibitor in industrial water treatment systems, particularly in cooling circuits and boilers. It protects copper and its alloys from degradation by forming a protective film on metal surfaces. Also serves as an intermediate in the synthesis of agrochemicals and pharmaceuticals, especially in the development of fungicides and plant growth regulators. Its derivatives exhibit biological activity, making it valuable in research for new active ingredients in crop protection products. Additionally, it functions as a ligand in coordination chemistry for creating metal-organic frameworks with potential catalytic applications.
