Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical industries. Its boronic ester structure enhances stability and handling compared to the free boronic acid, making it suitable for large-scale applications. Commonly employed in the preparation of biaryl compounds and functionalized aromatic systems found in active pharmaceutical ingredients. Also utilized in materials science for constructing conjugated systems in organic electronics.
