Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of protease inhibitors and other biologically active compounds. Its protected amino group (Boc) allows selective reactions in peptide synthesis, while the cyano group can be transformed into various functional groups such as carboxylic acids, amines, or tetrazoles, expanding its utility in drug development. Commonly employed in research settings for building complex organic molecules where controlled reactivity and stability are required.
