Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key building block for constructing carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its boronic ester group offers enhanced stability and reactivity, making it ideal for introducing chloro- and trifluoromethyl-substituted aryl moieties into complex molecules. It is particularly valuable in the development of bioactive compounds where the trifluoromethyl group improves metabolic stability and lipophilicity. Commonly employed in late-stage functionalization, it enables efficient diversification of aromatic scaffolds in drug discovery and materials science.
