Used in organic synthesis as a key intermediate for Suzuki-Miyaura cross-coupling reactions, enabling the formation of biaryl compounds in pharmaceutical development. Its boronic acid group facilitates carbon-carbon bond formation under mild conditions, making it valuable in constructing complex molecules for drug discovery. The presence of a chloroethylcarbamoyl group allows further functionalization or conjugation, useful in designing bioactive compounds and targeted therapies. Commonly applied in the preparation of protease inhibitors and other therapeutic agents where precise molecular architecture is critical.
