Used in organic synthesis as a key building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. Its boronic acid functionality allows for mild and selective coupling with aryl or heteroaryl halides, making it valuable in the preparation of complex quinazoline derivatives. These derivatives are often explored for their biological activity, particularly in medicinal chemistry for kinase inhibition and anticancer research. Also employed in the synthesis of functional materials and ligands for catalysis.
