Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) featuring pyrrolidine scaffolds. Its nitrile and protected amine functionalities allow for selective reactions, making it valuable in constructing complex molecules for drug discovery. Commonly employed in the preparation of dipeptidyl peptidase-4 (DPP-4) inhibitors used in type 2 diabetes treatments. Also utilized in organic synthesis for building chiral intermediates due to its stable ring structure and functional group compatibility.
