Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure supports the creation of bioactive molecules due to the presence of reactive sites for further functionalization. Commonly employed in medicinal chemistry for constructing indole-based drug candidates with potential antipsychotic, antidepressant, or anti-inflammatory activity. Also utilized in the preparation of fluorescent probes and agrochemicals owing to its stable aromatic framework and halogenated functional group.
