Used in organic synthesis as a boronic ester reagent for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical intermediates. Its protected boronic acid group enhances stability and selectivity during coupling, making it valuable in the preparation of complex aromatic compounds. Commonly applied in medicinal chemistry for constructing biaryl systems found in drug candidates. Also utilized in materials science for synthesizing conjugated polymers and organic electronic materials.
