Used primarily in organic synthesis, this compound acts as a reagent in the formation of carbon-carbon and carbon-heteroatom bonds. It is particularly effective in Stille coupling reactions, which are widely applied in the production of pharmaceuticals, agrochemicals, and advanced materials. Its organotin properties make it valuable in catalytic processes, enabling the creation of complex molecular structures with high precision. Additionally, it finds use in polymer chemistry, where it aids in the modification of polymer chains to achieve specific material properties. Its application is limited to controlled environments due to the toxic nature of organotin compounds.
