Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex aromatic systems. Commonly employed in Suzuki-Miyaura coupling reactions to form carbon-carbon bonds, enabling the creation of fluorinated and chlorinated biaryl motifs found in drug candidates. Also utilized in the preparation of protease inhibitors and anti-cancer agents due to its ability to enhance binding affinity and metabolic stability in target molecules.
