Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure supports the construction of complex indole-based molecules, making it valuable in medicinal chemistry for drug discovery. Commonly employed in the preparation of selective 5-HT6 and 5-HT7 receptor antagonists, which are investigated for treating cognitive disorders, depression, and schizophrenia. Also utilized in the synthesis of kinase inhibitors and other biologically active compounds in research settings.
