Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the development of serotonin reuptake inhibitors and other central nervous system agents. Its fluorinated benzofuran structure enhances metabolic stability and bioavailability in drug candidates. Also employed in the preparation of bioactive molecules for research in medicinal chemistry, where the fluorine atom improves binding selectivity and lipophilicity. Commonly utilized in late-stage functionalization strategies to optimize drug potency and pharmacokinetic profiles.
