Used primarily in the synthesis of high-performance polymers and resins, it acts as a key building block for creating materials with exceptional thermal stability and mechanical strength. Its tetracarboxylic structure allows it to form strong cross-linked networks, making it valuable in coatings, adhesives, and composite materials. Additionally, it is employed in the development of advanced electrolytes for batteries, enhancing ionic conductivity and stability. Its versatility also extends to organic synthesis, where it serves as a precursor for complex molecules in pharmaceuticals and fine chemicals.
