Used as an intermediate in the synthesis of high-performance polymers, particularly in the production of specialty polyesters and liquid crystalline polymers. Its chlorinated aromatic structure contributes to thermal stability and chemical resistance in the final polymer products. It is also employed in the development of flame-retardant materials due to the presence of chlorine atoms, which can suppress combustion. Additionally, it finds use in research settings for designing novel organic compounds with tailored electronic or structural properties.
