Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of nootropic drugs such as racetams. It plays a key role in modifying molecular structures to enhance blood-brain barrier penetration and improve metabolic stability. Commonly employed in research settings for creating analogs of pyrrolidone derivatives with cognitive-enhancing properties. Also utilized in the preparation of protected amino acid derivatives for peptide synthesis, where the tert-butoxycarbonyl (Boc) group provides reversible protection of the amine function.
