Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of indole-based drugs. Its iodine functionality allows for further modification through cross-coupling reactions such as Suzuki or Heck reactions, enabling the construction of complex molecular architectures. Commonly employed in medicinal chemistry for the preparation of serotonin receptor modulators and other bioactive molecules targeting neurological disorders. Also utilized in research settings to develop novel heterocyclic compounds with potential anticancer and anti-inflammatory properties.
