Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Particularly valuable in pharmaceutical and agrochemical industries for constructing biaryl compounds and functionalized aromatic systems. Its boronic ester group offers improved stability and handling compared to boronic acids, making it suitable for multi-step syntheses and large-scale applications. Also employed in the development of organic electronic materials and ligands for catalysis.
