Used as a key intermediate in the synthesis of high-performance polymers and specialty chemicals, particularly in the production of fluorinated polyimides and polyamides. Its trifluoromethyl group enhances thermal stability, chemical resistance, and solubility in organic solvents, making the resulting materials suitable for advanced electronics, aerospace components, and optoelectronic devices. Also employed in the development of pharmaceuticals and agrochemicals where fluorine substitution improves bioavailability and metabolic stability. Its rigid aromatic structure contributes to the formation of stable cyclic anhydrides, useful in catalysis and ligand design.
