Chemical Formula: Anhydrous: SnCl2; Dihydrate: SnCl2.2H2O
Molar Mass: Anhydrous: 189.60 g/mol; Dihydrate: 225.63 g/mol
CAS Number: Anhydrous: 7772-99-8; Dihydrate: 10025-69-1
Appearance: Anhydrous: White hygroscopic crystalline powder; Dihydrate: Colorless or white monoclinic crystals.
Solubility: Highly soluble in water (aqueous solution is acidic), ethanol, and acetone; insoluble in diethyl ether.

Main Applications
Chemical Industry:
Reducing Agent: Used in electroplating (e.g., tin plating), silver mirror reactions, and reduction of dye intermediates.
Stabilizer: As a heat stabilizer in the PVC industry to prevent polymer degradation.
Pharmaceuticals and Food:
Intermediate in synthesizing organotin compounds (e.g., anticancer drug precursors) in pharmaceuticals.
Formerly used as a food preservative (now restricted due to toxicity).
Analytical Chemistry:
Reducing agent for determining elements like silver, mercury, and arsenic; standard reagent in volumetric analysis.
Other Fields:
Flux in soldering to prevent metal surface oxidation.
Coloring agent in ceramic industry.

Safety and Hazards
Toxicity:
Moderately toxic; oral or inhalation may cause gastrointestinal symptoms (nausea, vomiting, diarrhea).
Long-term exposure may damage the liver and kidneys; irritating to skin and eyes.
Hazards:
Combustible when exposed to high heat; reacts violently with strong oxidizers (e.g., nitric acid, hydrogen peroxide).
Aqueous solutions are acidic; avoid contact with alkalis.
Protective Measures:
Wear gloves, goggles, and work in a well-ventilated area to prevent inhalation of dust/vapors.
Store in a dry, sealed container away from oxidizers, alkalis, and food chemicals.
Regulatory Status:
Not classified as a precursor chemical but is a hazardous chemical (corrosive substance), subject to the Regulations on the Safety Management of Hazardous Chemicals.

Notes
Solution Preparation: Dissolve solid in concentrated hydrochloric acid first, then dilute with water to inhibit hydrolysis.
Environmental Impact: Tin ions are toxic to aquatic life; wastewater must be treated before discharge to avoid water pollution.
