Used as a key intermediate in the synthesis of advanced organic materials, particularly in the preparation of functionalized polymers and liquid crystalline compounds. Its dual aldehyde groups enable cross-linking reactions, making it valuable in developing specialty resins and network polymers with tailored thermal and mechanical properties. It is also employed in pharmaceutical research for constructing complex molecular architectures through selective derivatization of the formyl functionalities. Additionally, it serves as a building block in supramolecular chemistry, facilitating the design of molecular receptors and sensors due to its rigid aromatic spacers and reactive sites.
