Application

This fluorinated dianhydride is primarily used as a monomer for synthesizing high-temperature-resistant polyimides in aerospace and microelectronics, where its trifluoromethyl groups enhance solubility and reduce dielectric constants. It also serves as a precursor for optical materials due to its rigid xanthene backbone and fluorinated aromatic structure. Applications extend to gas separation membranes and advanced composites requiring chemical inertness.
