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 structures. Its sterically hindered boronate ester group enhances stability and selectivity during coupling, making it suitable for late-stage functionalization of advanced intermediates. Also employed in materials science for designing organic semiconductors and functional polymers.
