Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its boronic ester functionality enables participation in Suzuki-Miyaura cross-coupling reactions, making it valuable in medicinal chemistry for constructing carbon-carbon bonds. The presence of both amino and hydroxyl groups allows for further functionalization, supporting its role in creating diverse compound libraries for drug discovery. It is also employed in the preparation of probes and sensors for detecting biologically relevant molecules due to the reactivity of the boronic acid moiety after deprotection.
