Used primarily in organic synthesis as a key intermediate for the preparation of various pharmaceuticals and biologically active compounds. It is particularly valuable in Suzuki-Miyaura cross-coupling reactions, which are widely employed to form carbon-carbon bonds in the synthesis of complex organic molecules. Its boronic acid group enables efficient coupling with aryl halides, making it a versatile building block for drug discovery and development. Additionally, it finds applications in the synthesis of materials for organic electronics and sensors due to its ability to form stable complexes with diols and other functional groups.
