Butyl(trichloro)stannane

Butyl(trichloro)stannane is an organotin compound with the molecular formula C4H9Cl3Sn and CAS number 1118-46-3. This chemical consists of a tin atom bonded to three chlorine atoms and one butyl group, giving it a molecular weight of 282.2 g/mol. It belongs to the family of organometallic compounds and serves as an important intermediate in various chemical processes.

Butyl(trichloro)stannane is typically a liquid at room temperature with characteristic organotin properties. As an organometallic compound containing tin and chlorine atoms, it exhibits moderate polarity and is sensitive to moisture. The compound has a molecular weight of 282.2 g/mol and contains both organic and inorganic components, making it soluble in organic solvents but reactive with water.

Butyl(trichloro)stannane is primarily used as an intermediate in organic synthesis and as a precursor for other organotin compounds. It serves in the production of specialized chemicals, catalysts, and materials in the pharmaceutical and chemical industries. The compound is particularly valuable in reactions requiring tin-based reagents and in the synthesis of complex organometallic structures.

Butyl(trichloro)stannane should be handled with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid contact with skin, eyes, and clothing, and ensure proper grounding when transferring the material to prevent static discharge.

Butyl(trichloro)stannane should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from heat sources and incompatible materials. Keep containers protected from moisture as organotin compounds can be hydrolytically unstable. Store away from strong oxidizing agents and bases, and maintain proper labeling and inventory records for traceability.

In case of skin contact with butyl(trichloro)stannane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately and seek medical advice if symptoms persist.

Butyl(trichloro)stannane must be disposed of as hazardous waste according to local and national regulations. Contact licensed waste disposal companies specialized in organometallic compounds. Never dispose of this material in regular waste streams or pour down drains. Maintain proper documentation of disposal activities and ensure compliance with environmental protection requirements.

Butyl(trichloro)stannane is classified as ADR Class 8 (corrosive substances), Packing Group II for transport purposes. This classification requires specific packaging, labeling, and documentation requirements for road transport. Proper UN-approved packaging must be used, and transport documents must include the correct shipping name and hazard identification numbers according to dangerous goods regulations.

Butyl(trichloro)stannane is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification obligations. While it is not currently listed as a Substance of Very High Concern (SVHC), users must comply with standard chemical safety requirements, workplace exposure limits, and proper risk assessment procedures as mandated by occupational health regulations.
