Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. Its structure allows for the introduction of lipophilic and electron-withdrawing groups, enhancing drug stability and bioavailability. Commonly employed in the preparation of anticonvulsants and antidepressants due to its ability to modulate receptor binding affinity. Also utilized in agrochemical research for designing novel pesticides with improved metabolic resistance.
