Used in pharmaceutical research as a key intermediate in the synthesis of central nervous system (CNS) agents. Shows potential in the development of antihistamines and anticholinergic drugs due to its structural affinity for histamine and muscarinic receptors. Also explored for its role in improving metabolic stability in drug candidates owing to the azetidine core and benzhydryl moiety. Investigated in the design of selective receptor antagonists with enhanced blood-brain barrier penetration.
