Acid base: Weakly basic, can react with acids to form salts
Reducibility: Can be oxidized by oxidants (hydrogen peroxide, potassium permanganate)
Complexation: Forms complexes with metal ions (Ag+, Au+, Cu²+)
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
