Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of serotonin receptor modulators and psychoactive drugs. Commonly found in research related to central nervous system agents, including potential antipsychotics and antidepressants. Also utilized in the preparation of tryptamine derivatives for neuropharmacological studies. Its piperazine-indole structure enhances binding affinity to various neurotransmitter receptors, making it valuable in drug discovery and medicinal chemistry.
