Used in organic semiconductor materials due to its extended aromatic structure and electron-accepting nitrile group. It serves as a key intermediate in the synthesis of fluorescent dyes and optoelectronic compounds. Its rigid fused-ring system enhances thermal stability and charge transport properties, making it suitable for applications in OLEDs and organic photovoltaics. Also explored in medicinal chemistry for developing kinase inhibitors owing to its ability to mimic purine scaffolds in biological systems.
