Used as a chiral building block in the synthesis of pharmaceutical intermediates, particularly in the preparation of β-amino acids and peptidomimetic compounds. Its protected amine and activated ester functionalities allow selective coupling reactions in multi-step organic syntheses. Commonly employed in the development of protease inhibitors and other bioactive molecules where stereochemistry is critical. The bromine atom serves as a leaving group, enabling further functionalization via nucleophilic substitution or cross-coupling reactions. Widely utilized in medicinal chemistry for structure-activity relationship studies.
