Used as an analytical reagent for the selective extraction and detection of metal ions, particularly in the separation of mercury and silver from aqueous solutions. Its structure allows strong coordination with soft metal ions, making it effective in hydrometallurgical processes and environmental monitoring. Also investigated as a corrosion inhibitor for metals in acidic media due to its ability to form protective films on metal surfaces. Shows potential in pharmaceutical research as a precursor for sulfur-containing heterocyclic compounds with biological activity.
