Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents and analgesics. Its structure allows for the introduction of cyclobutane motifs in drug candidates, enhancing metabolic stability and binding selectivity. Commonly employed in medicinal chemistry for building blocks in small molecule drug design. Also utilized in the preparation of peptidomimetics due to the presence of both amine and ester functionalities, enabling peptide bond formation and molecular diversification.
