Used primarily in organic synthesis as a key building block for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceuticals and agrochemicals. Its boronate ester group readily reacts with aryl halides in the presence of palladium catalysts, making it valuable for constructing biaryl frameworks found in functional materials and drug intermediates. The diol functionality enhances solubility in polar solvents and can assist in directing regioselective transformations or stabilizing intermediates during synthesis.
