Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require pyrrolidine-based structures. Its functionalized ring system with a bromine substituent allows for further chemical modifications through cross-coupling reactions, making it valuable in medicinal chemistry for creating drug candidates targeting central nervous system disorders, antiviral agents, and enzyme inhibitors. Commonly employed in research laboratories for building chiral molecules due to the potential for stereoselective transformations. Also utilized in the preparation of proline analogs and other nitrogen-containing heterocycles in organic synthesis.
