Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated active pharmaceutical ingredients (APIs) where the fluorine and trifluoromethyl groups enhance metabolic stability and binding affinity. Commonly employed in the production of anti-inflammatory, antiviral, and central nervous system agents. Its structure supports improved lipophilicity and bioavailability in drug candidates. Also utilized in agrochemicals for creating herbicides and pesticides with increased environmental persistence and efficacy. Frequently selected in medicinal chemistry for structure-activity relationship (SAR) studies due to its electron-withdrawing properties and ability to influence molecular conformation.
