Tributyltin chloride (TBTC) is an organotin compound widely used in organic synthesis and industrial applications. It serves as a catalyst, stabilizer, and reagent in the production of polymers, plastics, and silanes. In organic chemistry, it is employed for stannylation reactions, forming carbon–tin bonds that are useful intermediates in cross-coupling reactions like the Stille reaction. Additionally, TBTC has applications as a biocide, though its use in marine paints has declined due to environmental toxicity concerns.
