Used in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators, particularly targeting 5-HT2A and 5-HT2C receptors. It serves as a structural scaffold for developing compounds with potential antipsychotic, anxiolytic, and anti-obesity activities. Its tetrahydro-pyridoindole core enhances blood-brain barrier penetration, making it valuable in central nervous system drug design. Also explored in the development of selective ligands for neuroimaging and receptor binding studies.
