Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors. Its boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in medicinal chemistry for constructing biaryl structures. Commonly employed in the preparation of boron-containing drugs, including certain anticancer and antiviral agents. Also utilized in the design of enzyme inhibitors due to the ability of boron to interact with active site residues in target proteins.
