Monobutyltin Oxide(CAS: 2273-43-0)

Monobutyltin Oxide (CAS: 2273-43-0) is a colorless or white crystalline solid. It has a molecular weight of approximately 234.42 g/mol. This compound is poorly soluble in water but miscible with most organic solvents. It is moderately reactive and can undergo hydrolysis and oxidation reactions. It is used as a catalyst in various chemical processes and as a stabilizer in polymer formulations.

Monobutyltin Oxide is typically synthesized by reacting butyllithium with tin(II) chloride dihydrate in the presence of a suitable solvent. The reaction involves the displacement of a chloride ion from tin(II) chloride by the butyl group from butyllithium, forming the tin oxide compound. The reaction is usually conducted under an inert atmosphere to prevent side reactions and ensure purity.

Monobutyltin Oxide (CAS: 2273-43-0) is used in various industries. It is a key component in the production of organic tin compounds used as stabilizers in polymer formulations, particularly in the plastics and rubber industries. It also finds applications in the pharmaceutical industry as a precursor for other tin-based compounds and in the development of sensors and semiconductors.

When handling Monobutyltin Oxide (CAS: 2273-43-0), proper personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat should be worn. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate absorbent materials, and the area should be thoroughly washed down. Emergency showers and eye wash stations should be readily available. Refer to the Safety Data Sheet (SDS) for more detailed handling and disposal information.
