Used primarily in organic synthesis as a reagent for cross-coupling reactions, particularly in the formation of carbon-carbon bonds. It serves as a key intermediate in the production of pharmaceuticals and agrochemicals, enabling the introduction of pyrimidine moieties into complex molecules. Its organotin properties make it valuable in Stille reactions, facilitating the creation of biologically active compounds. Additionally, it is employed in material science for the development of organic electronic materials and ligands in catalysis.
