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 dissolved oxygen. Also employed in the synthesis of agrochemicals and pharmaceuticals due to its sulfur-rich heterocyclic structure, which can act as a building block for bioactive molecules. Additionally, it serves as a flotation agent in mineral processing for sulfide ores, enhancing the separation efficiency of valuable metals like copper and lead.
