Widely used in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key reagent for forming carbon-carbon bonds in organic synthesis. Its primary application lies in pharmaceutical and agrochemical research, where it enables the efficient construction of complex aromatic and biaryl structures. The boronate ester group readily participates in palladium-catalyzed coupling with aryl halides, making it valuable for building molecular frameworks in drug discovery and materials science. It is especially useful when introducing a 3-bromophenyl moiety into larger conjugated systems.
