Used in scientific research as a selective antagonist for serotonin receptors, particularly the 5-HT6 receptor subtype. It is employed to study cognitive functions, memory, and neurodegenerative disorders such as Alzheimer's disease. Due to its ability to cross the blood-brain barrier, it is valuable in behavioral and neurological studies in animal models. It has also been investigated for potential effects on appetite regulation and mood-related behaviors. Not intended for human therapeutic use and is restricted to laboratory research.
