Used primarily in the synthesis of pharmaceutical intermediates, especially in the development of tricyclic compounds with biological activity. Its rigid tricyclic structure serves as a core scaffold in medicinal chemistry for designing drugs targeting the central nervous system, including antidepressants and antipsychotics. Also employed in organic electronics due to its extended aromatic system, showing potential in the development of conductive or semiconductive materials. Its derivatization allows for tuning of electronic properties, making it useful in research settings for creating novel organic semiconductors.
