Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex pyridine-containing biaryl compounds. Its boronic ester group facilitates efficient carbon-carbon bond formation under mild conditions, making it valuable in pharmaceutical and agrochemical research. Commonly employed in the development of kinase inhibitors and other bioactive molecules due to the pyridine scaffold’s favorable binding properties. The pinacol protecting group enhances stability and handling while maintaining reactivity in catalytic transformations.
