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 hazardous with acute toxicity warnings and environmental concerns. The compound requires careful handling due to its potential health and environmental impacts, particularly its aquatic toxicity properties.

Tetracyclohexylstannane is an organotin compound that typically appears as a solid or liquid depending on temperature conditions. As an organic tin derivative with four cyclohexyl groups, it exhibits lipophilic characteristics and limited water solubility. The compound's molecular structure consists of a central tin atom bonded to four cyclohexyl rings, giving it significant molecular bulk and hydrophobic properties that influence its behavior in various chemical environments.

Tetracyclohexylstannane is primarily used as a catalyst or intermediate in organic synthesis and polymer chemistry applications. Its organotin structure makes it valuable in specialized chemical processes, particularly in research and development activities. The compound may also serve as a precursor for other organotin derivatives or as a specialized reagent in academic and industrial laboratories requiring specific tin-based chemistry functionalities.

Tetracyclohexylstannane requires careful handling 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 minimize inhalation exposure. Given its Acute Tox. 4 classification and GHS07 pictogram, avoid skin contact, ingestion, and inhalation. Implement proper hygiene measures and emergency procedures before handling this moderately toxic substance.

Tetracyclohexylstannane should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its environmental hazard classification (GHS09), prevent release to water systems and soil. Store separately from oxidizing agents and acids. Maintain proper labeling with hazard warnings and ensure storage areas comply with local chemical storage regulations for organotin compounds.

In case of skin contact with tetracyclohexylstannane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, rinse with clean water for 15 minutes and seek medical attention. For inhalation exposure, move to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician in case of exposure.

Tetracyclohexylstannane must be disposed of as hazardous chemical waste through licensed waste management companies specializing in organotin compounds. Due to its environmental hazard classification and aquatic toxicity, it cannot be discharged to sewers or waterways. Contact certified waste disposal services familiar with heavy metal-containing organic compounds. Follow local and European waste regulations (EU Waste Framework Directive) for proper classification and disposal procedures.

Tetracyclohexylstannane is classified under ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation purposes. This classification indicates it presents a moderate transport hazard requiring appropriate packaging, labeling, and documentation. Shipments must comply with ADR regulations for Class 9 substances, including proper packaging specifications, hazard labels, and transport documents. Use qualified dangerous goods carriers familiar with organotin compound transportation requirements.

Tetracyclohexylstannane is subject to European REACH regulation requiring registration for commercial use and CLP regulation for classification and labeling. While not currently listed as an SVHC (Substance of Very High Concern), its organotin nature may subject it to additional restrictions under specific national regulations. Users must comply with occupational exposure limits and environmental protection measures due to its aquatic toxicity classification.
