Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex isoquinoline derivatives with pharmaceutical relevance. Its boron-containing structure facilitates carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development of bioactive molecules. Commonly employed in the preparation of kinase inhibitors and other therapeutic agents targeting cancer and inflammatory diseases. Also applied in materials science for constructing conjugated organic frameworks used in optoelectronic devices.
