Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system (CNS) active compounds. Its protected indole structure allows selective functionalization at the nitrogen and aromatic ring positions, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in the preparation of drug candidates targeting neurological disorders, including antidepressants and antipsychotics. Also utilized in research settings for generating libraries of indole derivatives in high-throughput screening programs.
