Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its structure allows for easy modification in multi-step reactions, making it valuable in creating active pharmaceutical ingredients (APIs). Commonly employed in the preparation of β-lactam analogs and other heterocyclic compounds with biological activity. Also utilized in research settings for building complex organic molecules due to its functional group compatibility and ring strain properties from the oxetane moiety.
