Used as a key intermediate in the synthesis of fluorinated indole derivatives, which show potential in pharmaceutical research, particularly in the development of bioactive molecules with anti-inflammatory and anticancer properties. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Also employed in the preparation of fluorescent probes and optoelectronic materials due to the enhanced electron-withdrawing effect of the fluorine atom, improving photostability and emission characteristics.
