Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of serotonin receptor modulators and other neuroactive agents. Its structure supports the construction of complex indole-based molecules with potential activity in central nervous system disorders. Commonly employed in medicinal chemistry research for generating analogs in drug discovery programs targeting psychiatric and neurological conditions. Also utilized in the preparation of fluorescent probes and bioactive molecules due to its ability to undergo functionalization at multiple sites.
