Used in organic synthesis as a versatile building block, particularly in cross-coupling reactions like Stille coupling, to create complex pyridine derivatives. These derivatives are valuable in pharmaceutical research for developing drug candidates, especially in the design of compounds targeting neurological and inflammatory diseases. Additionally, it serves as a precursor in material science for synthesizing advanced organic materials with potential applications in electronics and optoelectronics. Its stability and reactivity make it a useful reagent in the development of novel chemical entities.
