Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of conjugated organic materials. It is particularly valuable in the development of organic semiconductors, OLEDs (organic light-emitting diodes), and pharmaceuticals due to its ability to introduce pyridine-based vinyl structures into larger π-conjugated systems. The boronate ester group enables efficient and selective bond formation with aryl or vinyl halides under mild palladium catalysis. Its (E)-configuration ensures structural rigidity and optimal electronic properties in the final products. Commonly employed in research and industrial settings for fabricating advanced functional materials.
