Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical industries. Its boronic acid functionality enables efficient carbon-carbon bond formation under mild conditions. Commonly employed in the preparation of biaryl compounds, which are structural motifs in active pharmaceutical ingredients. The ester group allows for further functionalization, enhancing its utility in multi-step syntheses. Stable and compatible with a variety of reaction conditions, making it suitable for library synthesis in drug discovery.
