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. Also applied in medicinal chemistry for modifying drug candidates to improve binding affinity and metabolic stability. Additionally, it serves as a building block in the preparation of protease inhibitors and other targeted therapies.
