Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners for textiles and paper. Its nitrile and ester functional groups allow for further chemical modifications, making it valuable in creating complex organic molecules for electronic materials, such as OLEDs and sensors. Also employed in research for developing metal-organic frameworks (MOFs) due to its rigid aromatic structure and ability to coordinate with metal ions. Shows potential in photovoltaic systems as a building block for light-harvesting compounds.
