Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of pharmaceuticals and agrochemicals. Its boronate ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in medicinal chemistry for constructing biaryl systems. Commonly employed in the development of kinase inhibitors and other bioactive molecules. Also applied in materials science for creating organic semiconductors and functional polymers due to its stable reactivity and good coupling yields.
