Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the development of serotonin receptor modulators and other neuroactive agents. Commonly employed in the preparation of indole-based drug candidates due to its halogen substitution pattern, which allows for selective cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations. Also utilized in research settings for the synthesis of fluorescent probes and agrochemicals.
