Used as a key intermediate in pharmaceutical synthesis, particularly in the preparation of kinase inhibitors for cancer treatment. Its boronic ester group enables Suzuki-Miyaura cross-coupling reactions, allowing efficient construction of complex drug molecules. The hydroxyl and amino functionalities provide sites for further chemical modification, enhancing solubility or binding affinity in final active pharmaceutical ingredients. Commonly employed in research and development of targeted therapies due to its versatility in forming carbon-carbon and carbon-nitrogen bonds under mild conditions.
