Used as a stabilizer and complexing agent in electroplating baths, particularly in cyanide-based plating solutions. Enhances the efficiency and uniformity of metal deposition by controlling the release of metal ions. Also serves as an additive in specialty chemical formulations for corrosion inhibition in industrial cooling systems. Its sulfur and cyanide groups contribute to strong coordination with transition metals, making it effective in metal recovery and wastewater treatment processes involving heavy metals.
