Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules in pharmaceutical and agrochemical industries. Its boronic ester structure enhances stability and handling compared to the free boronic acid, making it suitable for solid-phase synthesis and high-throughput screening. Commonly employed in the preparation of bioactive compounds, including drug candidates with aromatic frameworks. Also applied in materials science for constructing conjugated systems in organic electronics.
