Used primarily in medical research and ophthalmology, this compound acts as a muscarinic antagonist, helping to dilate pupils during eye examinations and surgeries. It is also employed in studies related to the central nervous system, particularly in investigating cholinergic pathways involved in memory and motion sickness. Due to its anticholinergic properties, it has been explored in the treatment of nausea and vomiting, especially in postoperative and motion sickness contexts, though its use is limited by poor central nervous system penetration. Additionally, it serves as a reference standard in pharmacological assays for receptor binding and inhibition studies.
