Used primarily in pharmaceutical research as a potent and selective antagonist of the 5-HT2A receptor, this compound is valuable in studying serotonin signaling pathways. It serves as a key tool in neuroscience for investigating the role of 5-HT2A receptors in mood, perception, and cognitive functions. Due to its high affinity and specificity, it is employed in receptor binding assays and functional studies to evaluate the pharmacological profiles of new psychoactive substances. Its structural properties also make it a reference compound in the development of antipsychotic and antidepressant drugs. Additionally, it has been utilized in positron emission tomography (PET) studies when labeled with radioactive isotopes, enabling in vivo imaging of 5-HT2A receptor distribution in the brain.
