Used as a key intermediate in the synthesis of active pharmaceutical ingredients, particularly in the development of fluorinated drugs where enhanced metabolic stability and bioavailability are desired. It serves as a trifluoromethylating agent in organic transformations, enabling the introduction of the trifluoromethyl group into target molecules. Employed in agrochemical manufacturing to produce herbicides and pesticides with improved resistance to degradation. Also utilized in materials science for modifying surface properties of polymers, enhancing chemical resistance and thermal stability. Its sodium salt form improves solubility and handling in aqueous reaction systems.
