Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of serotonin receptor modulators. Its structure supports the creation of bioactive molecules with potential applications in treating neurological and psychiatric disorders. The fluorinated aromatic ring enhances metabolic stability and binding affinity in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic phenyl rings while offering improved pharmacokinetic properties. Also utilized in the preparation of fluorinated heterocyclic compounds for PET imaging probes, where the fluorine atom facilitates radiolabeling.
