Used as a flotation agent in the mining industry to separate sulfide ores from gangue minerals. It enhances the recovery of metals like copper, lead, and zinc by selectively binding to sulfide surfaces, making them hydrophobic for effective froth flotation. Also serves as an intermediate in the synthesis of dithiocarbamate-based pesticides and rubber accelerators due to its reactivity with metal ions and organic compounds. Its chelating properties make it useful in metal deactivation and corrosion inhibition in industrial formulations.
