Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its strained azetidine ring enhances metabolic stability and binding affinity in drug molecules. Commonly employed in medicinal chemistry to improve pharmacokinetic properties such as solubility and bioavailability. Also utilized in the preparation of bioactive compounds targeting central nervous system disorders due to its ability to cross the blood-brain barrier.
