Used in organic synthesis as a key intermediate for the preparation of various pharmaceuticals, particularly in the development of enzyme inhibitors and receptor antagonists. It is also employed in cross-coupling reactions, such as Suzuki-Miyaura coupling, to create complex organic molecules with potential applications in drug discovery and material science. Additionally, it serves as a building block in the synthesis of bioactive compounds targeting diseases like cancer and inflammation. Its boronic acid group makes it valuable in the design of sensors and probes for detecting carbohydrates and other biomolecules.
