This chemical is primarily used as a reagent in organic synthesis, particularly in reactions involving the formation of carbon-carbon bonds. It is often employed in Stille coupling reactions, where it facilitates the cross-coupling of organic halides with organotin compounds to produce complex organic molecules. This process is widely utilized in the synthesis of pharmaceuticals, agrochemicals, and advanced materials. Additionally, it serves as a key intermediate in the preparation of various organotin compounds, which are used as stabilizers in plastics and as biocides in antifouling paints. Its role in these applications highlights its importance in industrial and research chemistry.
