Core Uses and Functions
1. Industrial Sector
Electroplating and Metal Treatment
- Corrosion inhibitor: Inhibit metal oxidation in acid gold plating and silver plating solution to improve coating uniformity (such as PCB circuit board gold plating process)
- Brightener: Combines with silver ions to form a complex to enhance the gloss of the coating (a key additive in the jewelry processing industry)
Textile Printing and Dyeing
- Antioxidants: Prevent dye oxidation and fading, improve the color fastness of cotton and silk fabrics (0.5-2%)
- Flame retardant treatment: Combined with phosphate, used for flame retardant modification of polyester fiber
2. Agricultural Applications
Fungicides and Plant Regulators
- Inhibition of fungal spore germination (e.g. control of rice blast), bactericidal by interfering with bacterial sulfur metabolism
- Promote the breaking of dormancy of tuber crops (potatoes, sweet potatoes) and increase germination rate (0.1% solution soaking treatment)
3. Medicine and Life Sciences
Drug Synthesis
- Synthesis of anti-thyroid drugs (e.g., methimazole), anti-HIV drugs (e.g., tenofovir intermediates)
- Sulfur sources in radiopharmaceutical labeling (e.g. ⁹⁹mTc labeled developer)
Biochemical Research
- Protein denaturant (concentration 2-4M for urea-thiourea double denaturation electrophoresis)
- DNA/RNA stabilizers (prevent nuclease degradation, for cryogenic sample preservation)
4. Environmental Protection and New Energy
Heavy Metal Wastewater Treatment
- Formation of complex precipitate with cadmium (Cd²+) and lead (Pb²+) (removal rate > 95% at pH 6-8)
Battery Material
- Lithium sulfur battery electrolyte additive, inhibition of polysulfide shuttle effect (2025 Ningde era patent technology)
- Used as an interface passivator in perovskite solar cells, increasing the photoelectric conversion efficiency to 26.8%
