Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and targeted cancer therapies. Its boronic acid functional group enables reversible interactions with biological targets such as enzymes, making it valuable in drug design for conditions like diabetes and viral infections. Commonly employed in Suzuki-Miyaura cross-coupling reactions to construct complex aromatic frameworks in medicinal chemistry. Also utilized in the preparation of covalent inhibitors due to its ability to form stable bonds with active site residues in proteins.
