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 research for constructing biaryl systems. Its bromonaphthalene moiety facilitates selective coupling, while the boronate ester group provides stability and reactivity under mild conditions. Commonly employed in the development of functional materials, including organic semiconductors and fluorescent dyes.
