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. Commonly applied in pharmaceutical and agrochemical research for constructing halogenated naphthalene derivatives with tailored biological activity. Its boronate ester group facilitates efficient coupling with aryl or heteroaryl halides under palladium catalysis, making it valuable in drug discovery and materials science. Stable and easy to handle, it supports high-yield transformations in late-stage functionalization of bioactive compounds.
