Used primarily in pharmaceutical research as a key intermediate in the synthesis of serotonin receptor modulators. It shows particular relevance in developing compounds targeting 5-HT3 and 5-HT6 receptors, which are involved in neurological and psychiatric disorders such as depression, schizophrenia, and cognitive impairment. Its structure allows for high binding affinity and selectivity, making it valuable in optimizing drug candidates for central nervous system activity. Also investigated for potential antipsychotic and antiemetic properties due to its interaction with neurotransmitter pathways.
