Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, especially in pharmaceutical and agrochemical industries. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in the development of bioactive compounds and functional materials. The phenolic hydroxyl group allows further modification, such as protection or conjugation, enhancing its utility in multi-step synthetic routes. Commonly employed in the preparation of drug candidates and advanced intermediates where aryl-aryl linkages are required.
