Used in organic synthesis as a key intermediate for the preparation of complex molecules, particularly in cross-coupling reactions like Stille coupling, which is essential for creating carbon-carbon bonds in pharmaceuticals and advanced materials. Its organotin component facilitates efficient and selective transformations, making it valuable in the development of drugs, agrochemicals, and functional materials. Additionally, it plays a role in the synthesis of heterocyclic compounds, which are crucial in medicinal chemistry for designing bioactive molecules.
