Used in the synthesis of advanced organic materials, particularly in the development of polycyclic aromatic compounds for electronic applications such as organic semiconductors and OLEDs. Its structural rigidity and electron-rich nature make it suitable as a building block in conjugated systems for optoelectronic devices. Also employed in the preparation of ligands for catalytic metal complexes and in research related to environmental pollutants, as it shares structural features with certain dioxin-like compounds.
