Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical synthesis. Its boronate ester group facilitates mild and selective coupling with aryl or heteroaryl halides, making it valuable in constructing complex nitrogen-containing molecules. Commonly applied in the development of active pharmaceutical ingredients (APIs), particularly in drug discovery for central nervous system (CNS) agents and kinase inhibitors. The hydrochloride salt form improves stability and handling in solid-state reactions.
