Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure allows for selective modification in drug design, enhancing binding affinity to specific receptors. Commonly employed in the development of serotonin receptor modulators due to the electron-withdrawing trifluoromethyl and sulfonamide groups, which improve metabolic stability and membrane permeability. Also utilized in agrochemical research for creating novel pesticides with improved efficacy and environmental profile.
