Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its structure allows for selective modifications, making it valuable in medicinal chemistry for building complex cyclic frameworks. Commonly employed in peptide-like synthesis and heterocyclic compound design, it supports the creation of protease inhibitors and receptor modulators. The presence of both carboxylic acid and protected amine functionalities enables stepwise coupling reactions, facilitating use in solid-phase and solution-phase synthesis for drug discovery research.
