Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of specialty polyketones and liquid crystalline polymers. Its rigid aromatic structure contributes to thermal stability and mechanical strength in polymer chains, making it valuable in aerospace, electronics, and automotive industries for manufacturing heat-resistant components. Also employed in the development of advanced coatings and adhesives where durability under extreme conditions is required. Additionally, it serves as a building block in organic synthesis for pharmaceuticals and agrochemicals due to its bifunctional reactivity.
