Butyltin Trichloride, identified by its CAS number 1118-46-3, is a significant organotin compound with a distinct set of chemical properties that lend themselves to crucial industrial applications. As a chemical supplier, understanding these characteristics is key to effectively serving R&D scientists and product formulators.

Chemically, Butyltin Trichloride possesses the molecular formula C4H9Cl3Sn and a molecular weight of approximately 282.18 g/mol. Its physical appearance is typically described as a clear yellow liquid. This liquid form, coupled with its solubility in most common organic solvents, makes it relatively easy to handle and incorporate into various manufacturing processes. Its density is reported around 1.693 g/mL at 25°C, and it has a boiling point of 226.8 °C at atmospheric pressure, though it boils at a lower temperature under reduced pressure.

The primary industrial utility of Butyltin Trichloride stems from its role as a precursor in chemical vapor deposition (CVD) for glass coating. When applied to glass surfaces at elevated temperatures, it decomposes to form a thin, transparent layer of tin dioxide (SnO2). This coating is highly valued for its ability to reflect infrared radiation, thus reducing heat transfer and improving energy efficiency in windows and architectural glass. For manufacturers of energy-efficient building materials or specialty glass, sourcing high-purity Butyltin Trichloride from a reliable chemical manufacturer is essential for achieving consistent coating quality.

Another critical application is its function as a heat stabilizer for Polyvinyl Chloride (PVC). PVC, while versatile, can degrade when exposed to heat and UV radiation, leading to discoloration and loss of mechanical properties. Butyltin Trichloride, as a component of organotin stabilizer systems, effectively scavenges free radicals and inhibits the degradation process. This application is widespread in the production of PVC pipes, films, and profiles, where longevity and performance are paramount. If you are a product formulator working with PVC, understanding the benefits and availability of this stabilizer from a dedicated supplier is key.

For R&D scientists exploring new material properties or optimizing existing formulations, Butyltin Trichloride also serves as a valuable chemical intermediate in organic synthesis. Its unique organometallic structure allows for the creation of diverse organotin derivatives with tailored functionalities.
