Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its boronic acid functional group enables Suzuki-Miyaura cross-coupling reactions, allowing efficient formation of carbon-carbon bonds in drug molecules. Commonly employed in medicinal chemistry for constructing biaryl systems found in bioactive molecules. Also utilized in the preparation of protease inhibitors and other targeted therapies due to its stability and reactivity profile in coupling reactions.
