Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure supports the construction of pyrrolidone-based compounds, which are found in certain enzyme inhibitors and neurologically active agents. Commonly employed in organic synthesis for ring formation and functional group manipulation due to its reactive carbonyl and ester groups. Also utilized in the preparation of peptidomimetics, helping to enhance metabolic stability and bioavailability in peptide-like drugs.
