Tetrachlorostannane

Tetrachlorostannane is an inorganic tin compound with the molecular formula Cl4Sn and CAS number 7646-78-8. This chemical substance has a molecular weight of 260.5 g/mol and is classified as a corrosive material. It belongs to the family of tin halides and is characterized by its high reactivity and corrosive properties, making it hazardous to handle without proper safety measures.

Tetrachlorostannane is typically a colorless to pale yellow liquid at room temperature with a pungent, irritating odor. It has a molecular weight of 260.5 g/mol and reacts violently with water, producing hydrochloric acid and tin compounds. The substance is highly corrosive and exhibits strong oxidizing properties, making it incompatible with many organic materials and metals.

Tetrachlorostannane is primarily used as a precursor in the synthesis of organotin compounds and as a catalyst in various chemical reactions. It serves as an intermediate in the production of tin-based materials and is utilized in specialized industrial processes requiring tin halide chemistry. The compound is also employed in research applications and in the manufacturing of certain electronic components.

Tetrachlorostannane must be handled with extreme caution due to its corrosive nature (Skin Corr. 1B classification). Essential protective equipment includes chemical-resistant gloves, safety goggles, face shields, and acid-resistant clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation of vapors. All handling procedures must comply with the GHS05 pictogram warnings indicating corrosive hazards.

Tetrachlorostannane must be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from moisture and incompatible materials. Storage areas should be equipped with appropriate containment systems and emergency equipment. The substance must be kept away from water, alcohols, and organic materials to prevent violent reactions and should be stored according to local chemical storage regulations.

Immediate action is required for any contact with tetrachlorostannane due to its corrosive properties. For skin contact, immediately flush with large amounts of water for at least 15 minutes and remove contaminated clothing. For eye contact, rinse continuously with water and seek immediate medical attention. In case of inhalation, move to fresh air immediately and consult a physician if respiratory irritation occurs.

Tetrachlorostannane disposal must comply with local and international hazardous waste regulations due to its corrosive and environmentally harmful properties (Aquatic Chronic 3). The substance should never be poured down drains or released into the environment. Disposal must be carried out by licensed waste management companies specialized in handling corrosive chemicals, following appropriate neutralization and treatment procedures.

Tetrachlorostannane is classified as ADR Class 8 (corrosive substances) with Packing Group II, indicating moderate danger level during transport. Transportation requires appropriate UN-specification packaging designed for corrosive liquids, proper labeling with corrosive hazard symbols, and compliance with ADR regulations. Drivers and handlers must be trained in hazardous materials transport and emergency response procedures.

Tetrachlorostannane is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification as a corrosive substance (Skin Corr. 1B). It is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational safety regulations, environmental protection laws, and proper classification and labeling requirements under GHS standards.

Tetrachlorostannane is available through OYSI, a specialized European distributor of technical chemicals. As an established chemical supplier, OYSI can provide this corrosive compound to qualified industrial and research customers with appropriate handling capabilities. Due to the hazardous nature of this substance, purchases typically require verification of proper storage facilities and safety protocols.
