Used as a key intermediate in the synthesis of anticholinergic drugs, particularly in the development of bronchodilators for treating respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). Its structure supports binding to muscarinic receptors, making it valuable in designing medications that inhibit acetylcholine activity in the airways. Also explored in the research of central nervous system agents due to its ability to cross the blood-brain barrier, with potential applications in treating neurological disorders.
