Thermal stability: Decomposes when heated above melting point, producing ammonia and hydrogen sulfide
Hydrolysis reaction: Hydrolyzes under acidic/alkaline conditions to produce urea and hydrogen sulfide

Industrial Applications

1. Metal Surface Treatment and Plating

Plating additives: Brightener/leveling agent for silver, gold, and zinc plating processes
Acid copper plating: Inhibits copper ion precipitation, improves coating binding force
Metal corrosion inhibitor: Added to pickling solutions (hydrochloric/sulfuric acid) to slow corrosion

2. Rubber and Plastics Industry

Vulcanization accelerator: Precursor for secondary sulfonamide accelerators
Plastic stabilizer: Used in PVC to inhibit thermal degradation and oxidation

3. Synthesis of Medicine and Pesticides

Pharmaceutical intermediates: Key ingredient for sulfur-containing drugs
Pesticide synthesis: Intermediate for insecticides, fungicides, and herbicides

4. Chemical Synthesis and Catalyst

Reducing agent: Reduces nitro compounds to amino compounds
Sulfur sources and ligands: Used for synthesis of thioamide and thiocarbamate

5. Textile and Printing Industry

Printing and dyeing auxiliary: Reducing agent for vat dye leucochromes
Flame retardant precursors: For synthetic sulfur-containing flame retardants

6. Environmental Protection

Heavy metal adsorption: Forms complexes with heavy metal ions in wastewater
Flue gas desulfurization: Auxiliary absorber to enhance desulfurization efficiency

7. Other Applications

Photosensitive material: Component in photographic development solutions
Analytical Chemistry: Masking agent or color developing agent for metal ion analysis
