Used in organic synthesis as a chiral catalyst or ligand in asymmetric reactions, particularly in enantioselective transformations involving carbon–carbon bond formation. Its complex polycyclic framework with phosphorus and oxygen heteroatoms enables strong coordination to transition metals, making it suitable for catalytic applications in pharmaceutical intermediates and fine chemical production. The bromo and methoxy substituents enhance electronic tuning and steric control, improving selectivity in stereoselective processes. Also investigated for potential use in materials science due to its rigid, extended aromatic system and ability to form stable metal complexes.
