This compound is primarily used as a reagent in organic synthesis, particularly in Stille cross-coupling reactions to introduce the 3-pyridyl group into aryl, vinyl, or acyl halides using palladium catalysis. It plays a key role in constructing complex molecular structures for pharmaceuticals, agrochemicals, and advanced materials. In research, it serves as a building block for pyridyl-containing molecules valuable in medicinal chemistry and cross-coupling methodologies. While organotin compounds in general are used in catalysts and PVC stabilizers, this niche pyridine derivative is mainly applied in synthetic transformations rather than commodity stabilization or broad catalysis.
