Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates targeting central nervous system disorders. Its azetidine core provides structural rigidity and metabolic stability, making it valuable in medicinal chemistry for optimizing pharmacokinetic properties. Commonly employed in the preparation of enzyme inhibitors and receptor modulators due to its favorable ring strain and polarity. Also utilized in the construction of peptidomimetics, where it serves as a constrained building block to enhance binding affinity and selectivity.
