Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and kinase inhibitors. Its boronic acid functional group enables participation in Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing complex organic molecules for drug discovery. Commonly employed in the preparation of bioactive molecules targeting diseases such as diabetes, cancer, and inflammatory conditions. Also utilized in the design of covalent inhibitors due to the reactivity of the boronic acid moiety with serine residues in enzyme active sites.
