Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its protected azetidine ring provides structural stability and enables selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic compounds. Commonly employed in the preparation of enzyme inhibitors and receptor modulators due to the ring’s favorable metabolic and conformational properties. Also utilized in research settings for scaffold diversification in high-throughput screening libraries.
