Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, this compound enables the formation of carbon-carbon bonds in the synthesis of complex organic molecules. Its boronate ester group facilitates palladium-catalyzed coupling with aryl or heteroaryl halides, making it valuable in pharmaceutical and agrochemical research. It is particularly useful in constructing polycyclic and nitrogen-containing frameworks found in bioactive compounds. The rigid, fused ring structure enhances selectivity and stability during reactions, improving yields in target molecule assembly.
