1,3-Isobenzofurandione, 5,5′-sulfonylbis-(CAT: L015371) is a bifunctional aromatic compound composed of two phthalic anhydride units bridged by a sulfonyl (-SO₂-) linkage. This reagent is widely employed in polymer chemistry, particularly in the synthesis of high-performance polyimides and thermosetting resins, due to its excellent thermal stability and electron-withdrawing properties. The anhydride groups offer reactive sites for condensation with diamines or diols, enabling the formation of heat-resistant, mechanically robust materials. It is also useful in the preparation of advanced functional materials for electronics, coatings, and aerospace applications, where resistance to thermal and oxidative stress is essential for long-term durability.
