Used in organic synthesis as a key intermediate for Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical development. The boronate ester group facilitates coupling with aryl halides under palladium catalysis, while the cyanoethyl-protected amide allows for further functionalization or deprotection to yield bioactive molecules. Commonly applied in the preparation of conjugated aromatic systems for materials science and drug discovery.
