Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of indole-based drugs. Its structure supports the construction of complex molecules in medicinal chemistry, especially in routes requiring functionalization at the indole nitrogen and selective substitution on the aromatic ring. The iodine moiety allows for further transformations via cross-coupling reactions, enabling the introduction of diverse groups for drug optimization. Commonly employed in research settings for creating analogs in serotonin receptor modulators and other neuroactive agents.
