Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its structure supports the construction of complex molecules where a constrained azetidine ring enhances metabolic stability and bioavailability. Commonly employed in medicinal chemistry for modifying drug candidates to improve solubility and binding affinity. Also utilized in the preparation of protease inhibitors and kinase inhibitors due to its ability to act as a scaffold in structure-activity relationship studies.
