Used primarily in pharmaceutical research as a key intermediate in the synthesis of central nervous system (CNS) active compounds. Its structural features make it valuable in developing antihistamines and anticholinergic agents. The compound's ability to cross the blood-brain barrier enhances its utility in targeting neurological pathways. It has also been explored in the development of treatments for sleep disorders and motion sickness due to its influence on histamine and muscarinic receptors. Additionally, its derivative potential supports ongoing research into cognitive enhancers and antidepressants.
