Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its boronic acid group enables Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing complex aromatic frameworks for drug discovery. The aldehyde and hydroxyl functionalities allow further derivatization, facilitating the creation of diverse molecular structures in medicinal chemistry research. Commonly employed in the preparation of protease inhibitors and anti-inflammatory agents.
