Trimethyltin chloride, also known as Chlorotrimethylstannane or Me₃SnCl, is an organotin compound with the molecular formula C₃H₉ClSn and a molecular weight of 199.27 g/mol. This compound features tin in a +4 oxidation state, coordinated with three methyl groups and a chloride ion, creating a stable, yet reactive, structure. Typically appearing as a colorless liquid or solid, Trimethyltin chloride has a purity of 98%+, verified by gas chromatography. Due to its moisture sensitivity, it should be stored in a dry, sealed container to maintain stability.
Trimethyltin chloride is commonly used in organotin chemistry and as a precursor for synthesizing various tin-containing compounds. It serves as a reagent in organic synthesis, specifically in processes requiring the transfer of methyl or tin moieties to form complex organometallic structures. Its ability to selectively introduce the trimethyltin group makes it particularly valuable in research, where precise control over synthesis reactions is necessary.
Classified with hazard codes H300, H310, H315, H319, H330, H335, H336, H373, H400, and H410, Trimethyltin chloride is both highly toxic and potentially hazardous. Protective equipment such as gloves, goggles, and respiratory protection is essential to prevent ingestion, skin contact, or inhalation of fumes. Due to its sensitivity to moisture, the compound should be stored in a dry environment, ideally in tightly sealed containers away from direct sunlight and sources of heat.
In industrial and laboratory contexts, Trimethyltin chloride plays a critical role in synthesizing high-purity organotin compounds and is widely applied in material science and chemical research. Its use in producing organotin reagents supports the development of new chemical products and polymers, while its stability under controlled conditions makes it essential in various organometallic transformations. The compound’s unique properties make it highly relevant in the fields of advanced materials, catalyst research, and synthetic chemistry.
Trimethyltin chloride is used as a source of the trimethylstannyl group. Organotin compounds derived from this product are useful in organic synthesis, especially in radical chain reactions. Me3SnCl is also applied as a precursor to compounds used in PVC stabilization. See links below
