Stannous chloride - for Industry, agriculture
Product Introduction
Stannous chloride (SnCl 2 , CAS 7772-99-8) is a white crystalline tin(II) salt and strong reducing agent, soluble in water and alcohol. It is used in electroless plating sensitization, dyeing, chemical and polymer production, Tc-99m radiopharmaceuticals, food anti-browning, and ceramics, glass, enamel and ink.
Product Overview
Stannous chloride, also called tin(II) chloride (SnCl 2 , CAS 7772-99-8), is an inorganic tin(II) salt supplied as a white crystalline solid, soluble in water and alcohol. It is a strong reducing agent that readily converts to tin(IV), so it should be kept sealed. It is used as a sensitizer in electroless plating, a mordant in dyeing, a reducing agent in chemical and polymer production, and in the preparation of technetium-99m radiopharmaceuticals, food preservation and ceramic and glass products.

Key Benefits
- Strong reducing agent for chemical processing
- Standard sensitizer in electroless plating that improves adhesion
- Mordant in dyeing processes
- Used in preparing technetium-99m radiopharmaceuticals
- Anti-browning preservative for permitted food uses
Applications
- Electroless plating — sensitizes metal and non-metal surfaces before deposition of other metals
- Dyeing and textiles — mordant in dyeing; historical slimicide and biocide uses are now regulated
- Chemical and polymer production — reducing agent in manufacturing
- Medical diagnostics — preparation of technetium-99m radiopharmaceuticals
- Food and agriculture — prevents discoloration and oxidation in permitted applications, including certain canned products
- Other industrial uses — toothpaste, ceramics, porcelain, enamel, glass and ink
Safety, Packing & Storage
Stannous chloride may be toxic and irritating and has potential environmental impact. Wear gloves, goggles and protective clothing, ensure ventilation, and keep the product sealed in a cool, dry place to prevent oxidation and moisture uptake.
