Used primarily as a key intermediate in pharmaceutical synthesis, especially in Suzuki-Miyaura cross-coupling reactions to construct biaryl or heteroaryl frameworks found in bioactive molecules. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development. Commonly employed in the preparation of kinase inhibitors and other therapeutic agents targeting cancer and inflammatory diseases. Its stability and reactivity profile allow for high yields and selectivity in late-stage functionalization of complex molecules.
