Used primarily in research settings to investigate serotonin receptor function, particularly the 5-HT2A receptor subtype. It serves as a pharmacological tool to block these receptors, helping scientists study their role in conditions like hypertension, schizophrenia, migraine, and platelet aggregation. Due to its ability to modulate vascular tone, it has been explored in studies related to blood pressure regulation and cerebral circulation. Also used in behavioral neuroscience to examine the impact of serotonin signaling on mood, perception, and cognition. Not approved for clinical use in most countries but remains valuable in experimental pharmacology.
