Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex biaryl compounds in pharmaceutical and agrochemical development. Its boronate ester group facilitates efficient carbon-carbon bond formation under mild conditions, making it valuable in medicinal chemistry for constructing drug-like molecules. Commonly employed in the preparation of kinase inhibitors and other bioactive structures where aromatic ring systems are required. Also utilized in materials science for designing organic semiconductors and functional polymers due to its stability and reactivity profile.
