Germany and the United States are the leading exporters of Butyltin trichloride (CAS 1118-46-3), accounting for the largest shares of global shipments in recent years, while China, India, and South Korea represent the top importing markets. Trade volumes have remained relatively stable since 2022, with modest fluctuations in Butyltin trichloride prices reflecting consistent industrial demand in PVC stabilizer manufacturing.
Butyltin trichloride is a colorless to pale yellow, fuming liquid with a pungent, acrid odor and high volatility; it decomposes before boiling and has a melting point of approximately −20 °C. It is classified as an organotin compound and functions primarily as a reactive synthetic intermediate. Industrially, it serves as a key precursor in the production of other organotin derivatives—particularly dibutyltin dilaurate and monobutyltin oxide—used as catalysts and stabilizers. Its principal applications are in the polymer industry, especially as a catalyst for polyurethane foam formation and silicone curing, and as a stabilizer in polyvinyl chloride (PVC) formulations.
