Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents and antidepressant drugs. Its structure allows for selective modification, making it valuable in creating bioactive molecules with enhanced metabolic stability and binding affinity. Commonly employed in medicinal chemistry for constructing fluorinated aromatic building blocks, which improve drug lipophilicity and membrane permeability. Also utilized in the preparation of agrochemicals and functional materials where fluorine substitution plays a critical role in performance.
