Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of beta-lactam antibiotics. Its strained azetidine ring enhances reactivity in coupling reactions, making it valuable in medicinal chemistry for constructing complex amine-containing molecules. It is also employed in the preparation of enzyme inhibitors and receptor modulators due to its favorable pharmacokinetic properties and structural rigidity. Commonly utilized in research settings for designing novel drug candidates targeting bacterial infections and central nervous system disorders.
