Used as a key intermediate in pharmaceutical synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to form biaryl compounds. Its boronic ester group enables efficient carbon-carbon bond formation under mild conditions, making it valuable in the development of active pharmaceutical ingredients (APIs). Commonly applied in the production of kinase inhibitors and other nitrogen-containing heterocyclic drugs. The presence of both cyano and chloro functionalities allows for further derivatization, enhancing its utility in drug discovery and medicinal chemistry research.
