Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, particularly in pharmaceutical and agrochemical research. Its boronic ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in drug discovery for building biaryl and heterobiaryl structures. The cyclobutane ring adds structural rigidity, which can enhance metabolic stability and influence the three-dimensional shape of target compounds. Commonly employed in late-stage functionalization due to its stability and reactivity profile.
