Primarily used in pharmacological research as a selective agonist for the 5-HT3 receptor, which is involved in various neurological and gastrointestinal processes. It is often employed in studies to understand the role of 5-HT3 receptors in conditions like nausea, vomiting, and anxiety. Additionally, it serves as a tool compound in experimental models to investigate neurotransmitter release and receptor signaling pathways. Its application extends to the development of therapeutic agents targeting 5-HT3 receptor-related disorders.
