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 coupling with aryl or vinyl halides under palladium catalysis, making it valuable in pharmaceutical development and materials science. The amine functionality, protected as a hydrochloride salt, can be further modified after coupling, allowing for diverse structural elaboration. It is especially useful in medicinal chemistry for constructing biaryl systems found in bioactive compounds.
