Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure supports the construction of complex amines and heterocyclic compounds, making it valuable in medicinal chemistry for optimizing potency and selectivity. Commonly employed in the preparation of protease inhibitors and receptor modulators due to its favorable steric and electronic properties. Also utilized in solid-phase and solution-phase peptide-like synthesis where protection of the amine function is required.
