Used as a key intermediate in the synthesis of indole-based pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its protected indole structure allows selective functionalization at the nitrogen and carbon positions, making it valuable in medicinal chemistry for constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form C–C bonds, enabling the preparation of diverse indole derivatives for biological screening. Also utilized in the preparation of tryptamine and tryptophan analogs with potential therapeutic activity.
