Used primarily in the pharmaceutical industry as a key chiral intermediate in the synthesis of potent antihistamines and central nervous system agents. Its rigid azetidine backbone and defined stereochemistry make it valuable for developing drugs with high selectivity and improved metabolic stability. Commonly employed in the production of wake-promoting agents for the treatment of sleep disorders such as narcolepsy and obstructive sleep apnea. Also explored in research for cognitive enhancers and treatments for neurological conditions due to its ability to cross the blood-brain barrier efficiently.
