Used in pharmaceutical research as a key intermediate for developing central nervous system (CNS) active compounds. Shows potential in the synthesis of serotonin receptor modulators, particularly targeting 5-HT3 and 5-HT6 receptors, which are involved in mood regulation, cognition, and nausea control. Investigated for use in treatments of psychiatric disorders such as depression, anxiety, and schizophrenia. Also explored for analgesic applications due to structural affinity with known pain-modulating agents. Its piperidine-indole framework supports blood-brain barrier penetration, making it suitable for neuropharmacological drug design.
