Used in the synthesis of pharmaceutical intermediates, particularly in the development of serotonin receptor modulators and other neuroactive compounds. Its structure supports the construction of complex indole-based molecules with potential activity in central nervous system disorders. Commonly employed in research settings for creating novel analogs in medicinal chemistry programs. Also utilized in the preparation of fluorescent probes and imaging agents due to the electron-withdrawing properties of the cyano and fluoro groups enhancing photostability and signal detection.
