Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its boronic acid group enables Suzuki-Miyaura cross-coupling reactions, allowing efficient construction of biaryl structures in drug molecules. Also employed in the preparation of protease inhibitors and anti-inflammatory agents due to its ability to enhance binding affinity and metabolic stability. Commonly utilized in medicinal chemistry for lead optimization in drug discovery programs.
