Used as a key intermediate in the synthesis of various pharmaceutical compounds, particularly in the development of kinase inhibitors. It is also employed in Suzuki-Miyaura cross-coupling reactions to create complex organic molecules for drug discovery and material science. Its boronic ester group makes it valuable in bioconjugation and labeling applications in biochemical research. Additionally, it serves as a building block in the preparation of advanced materials with potential applications in organic electronics and optoelectronics.
