Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its strained azetidine ring enhances binding selectivity in drug candidates, making it valuable in medicinal chemistry for central nervous system agents and kinase inhibitors. Commonly employed in asymmetric synthesis to introduce stereochemical control. Also utilized in the preparation of intermediates for agrochemicals and specialty chemicals where three-dimensional molecular architecture improves biological activity.
