Used as a key intermediate in pharmaceutical synthesis, particularly in the preparation of kinase inhibitors and other biologically active compounds. Its boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, allowing efficient formation of carbon-carbon bonds in heterocyclic systems. Commonly employed in the development of drug candidates targeting cancer and inflammatory diseases due to its ability to enhance binding affinity and metabolic stability. Also utilized in the synthesis of labeled compounds for biochemical assays and imaging studies.
