Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its boronic acid functional group enables participation in Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing biaryl structures found in bioactive molecules. Commonly employed in medicinal chemistry for lead optimization due to its ability to enhance binding affinity and metabolic stability. Also utilized in the preparation of protease inhibitors, especially targeting serine proteases involved in disease pathways.
