Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronic ester functionality provides enhanced stability and reactivity, making it valuable for constructing biaryl compounds and complex organic molecules. Commonly employed in the development of active pharmaceutical ingredients (APIs) where precise molecular architecture is required. The pinacol protecting group facilitates handling and storage while maintaining high coupling efficiency under mild reaction conditions.
