Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its boronic acid functionality enables participation in Suzuki-Miyaura cross-coupling reactions, making it valuable in constructing complex aromatic frameworks found in drug candidates. Commonly employed in medicinal chemistry for lead optimization due to its ability to enhance binding affinity and metabolic stability. Also utilized in the preparation of sensors and functional materials where phenolic and boronic acid groups can interact with diols or metal ions.
