Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other neuroactive compounds. Its structure supports the construction of complex indole-based molecules found in bioactive agents. Commonly employed in research settings for the preparation of analogs in medicinal chemistry, especially targeting central nervous system disorders. Also utilized in the creation of novel heterocyclic compounds for drug discovery and in the study of structure-activity relationships within indole derivatives.
