Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation reactions. It forms part of transition metal catalysts that enable the efficient synthesis of optically active compounds, which are important in pharmaceuticals and fine chemicals. Its rigid ferrocene backbone and well-defined stereochemistry enhance enantioselectivity and catalytic activity, especially in the hydrogenation of prochiral olefins and ketones. Commonly employed in the production of chiral intermediates where high enantiomeric excess is required.
