Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where the Boc-protected pyrrolidine scaffold is required. The chloromethyl group allows for further alkylation or functionalization, enabling the construction of complex nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for drug discovery programs targeting central nervous system agents, enzyme inhibitors, and receptor modulators. Its protected amine group ensures selective reactivity, making it valuable in multi-step organic syntheses.
