Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective organic transformations. Its rigid biimidazole backbone and chiral environment make it effective in coordinating transition metals for catalytic reactions such as asymmetric hydrogenation and C–C bond formation. The isopropyl groups enhance steric hindrance, improving enantioselectivity. Commonly applied in pharmaceutical synthesis where high optical purity is required. Also investigated in organocatalysis due to its ability to form stable hydrogen-bonded complexes with substrates.
