Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports blood-brain barrier penetration, making it valuable in designing neuroactive drugs. Commonly employed in medicinal chemistry for optimizing pharmacokinetic properties such as metabolic stability and solubility. Also utilized in the preparation of bioactive molecules where a constrained amine moiety is required. Its oxetane ring contributes to improved binding affinity and reduced lipophilicity in drug candidates.
