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 for investigating memory, motion sickness, and neurotransmitter regulation. Due to its ability to cross the blood-brain barrier, it serves as a tool in neuroscience for modeling cognitive impairments and testing potential treatments. Additionally, it has been explored in controlled settings for managing certain gastrointestinal and respiratory spasms.
