Used primarily 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 construction of complex indole-based molecules, making it valuable in medicinal chemistry for drug discovery. Commonly employed in research settings to prepare analogs for biological evaluation, especially in studies related to neurological disorders and migraine treatments. Also utilized in the preparation of agrochemicals and bioactive compounds due to its reactive functional groups and halogen substitution pattern.
