Tetracyclohexylstannane

Tetracyclohexylstannane is an organotin compound with the molecular formula C24H44Sn and CAS number 1449-55-4. This chemical substance has a molecular weight of 451.3 g/mol and belongs to the family of tetraalkyltin compounds. It is classified as moderately toxic (Acute Tox. 4) and poses environmental hazards to aquatic life. The compound displays GHS07 and GHS09 pictograms, indicating health and environmental warnings respectively.

Tetracyclohexylstannane is a solid organometallic compound at room temperature with a molecular weight of 451.3 g/mol. As an organotin derivative with four cyclohexyl groups attached to a central tin atom, it typically exhibits low water solubility due to its highly hydrophobic cyclohexyl substituents. The compound's physical appearance and specific properties like melting point and density require specialized analytical characterization due to its complex molecular structure.

Tetracyclohexylstannane serves primarily as a specialized organotin reagent in research and industrial applications. It is commonly used as a catalyst or intermediate in organic synthesis reactions, particularly in polymer chemistry and materials science. The compound may also function as a precursor for other organotin derivatives or as a specialized additive in certain chemical processes requiring tin-based compounds with specific steric properties provided by the cyclohexyl groups.

Tetracyclohexylstannane requires careful handling due to its Acute Tox. 4 classification across multiple exposure routes. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and appropriate respiratory protection when handling powders or in poorly ventilated areas. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin and eye contact, and ensure thorough washing after handling to prevent accidental ingestion.

Tetracyclohexylstannane should be stored in a cool, dry, well-ventilated area away from incompatible materials and ignition sources. Use tightly sealed, chemically compatible containers to prevent contamination and exposure. Storage areas should be equipped with appropriate spill containment measures due to the compound's environmental hazards (Aquatic Acute 1, Aquatic Chronic 1). Implement restricted access protocols and maintain proper inventory management to ensure safe handling and regulatory compliance.

Immediate action is required upon contact with tetracyclohexylstannane due to its toxicity classification. For skin contact, remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek medical attention. Always consult safety data sheets for specific first aid measures.

Tetracyclohexylstannane waste must be disposed of as hazardous waste according to local and European regulations due to its toxicity and environmental impact classifications. The compound cannot be disposed of through regular waste streams and requires specialized hazardous waste management services. Container disposal should follow local regulations, with proper labeling and documentation throughout the disposal process. Consult local environmental authorities and certified waste disposal companies for compliant disposal procedures.

Tetracyclohexylstannane is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation purposes. This classification requires specific packaging, labeling, and documentation according to European transport regulations. Shipments must include proper hazard labels, transport documents, and emergency response information. Only qualified carriers experienced in handling Class 9 materials should transport this substance, ensuring compliance with all applicable national and international transport regulations.

Tetracyclohexylstannane is subject to European chemical regulations including REACH and CLP classifications. The compound is not currently listed as a Substance of Very High Concern (SVHC), but its toxicity and environmental hazard classifications require compliance with standard chemical safety regulations. Users must ensure proper risk assessments, safety data sheet distribution, and worker protection measures are implemented. Export/import activities may require additional documentation depending on destination countries and quantities involved.
