Used as a key intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, which are essential for creating complex organic molecules like pharmaceuticals and advanced materials. Its boronic acid group enables efficient coupling with aryl halides, making it valuable in producing compounds for drug development and organic electronics. Also employed in the preparation of OLED materials due to its ability to form stable conjugated systems, enhancing device performance. Additionally, it serves as a building block in the synthesis of polymers and ligands for catalytic applications.
