Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of peptide-based drugs. The presence of the cyanophenyl group and the protected amine (Boc group) makes it valuable in solid-phase peptide synthesis and in constructing complex molecules where selective reactivity is required. It is also employed in the preparation of enzyme inhibitors and receptor ligands, especially in research targeting neurological and metabolic disorders. Its functional groups allow for further chemical modifications, enabling the creation of diverse compound libraries for drug discovery.
