Used primarily in scientific research to study the role of serotonin receptors, particularly the 5-HT6 receptor subtype. It acts as a selective antagonist, helping researchers understand cognitive functions, memory processes, and potential pathways involved in neurodegenerative diseases like Alzheimer's. Due to its ability to cross the blood-brain barrier, it is valuable in behavioral and neurological studies in animal models. Investigated for potential therapeutic applications in improving cognitive deficits and modulating neurotransmitter systems involved in learning and memory. Not used in clinical medicine; limited to experimental and pharmacological research.
