Used primarily as a research compound in biochemical and pharmacological studies, particularly as an inhibitor of acetylcholinesterase (AChE). It aids in investigating the role of acetylcholine in the nervous system, especially in research related to neurological disorders such as Alzheimer's disease or myasthenia gravis. Additionally, it serves as a starting material for synthesizing other structurally similar compounds in the laboratory, which may hold potential for future drug development.
