Used in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly in the development of serotonin receptor modulators. Its halogenated indole structure makes it valuable for constructing complex heterocyclic systems found in neuroactive drugs. Also employed in the study of fluorinated analogs to improve metabolic stability and binding affinity in central nervous system agents. Commonly utilized in medicinal chemistry for scaffold modification and structure-activity relationship (SAR) studies.
