Used as a corrosion inhibitor in industrial water treatment systems, particularly for copper and its alloys. It forms a protective film on metal surfaces, preventing oxidation and degradation caused by water and oxygen exposure. Also employed in the electronics industry to safeguard copper components during manufacturing and storage. Additionally, it serves as an intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive heterocyclic structure. Its metal-chelating properties make it useful in analytical chemistry for detecting or removing trace metal ions.
