Used as a chiral ligand in asymmetric synthesis, particularly in catalytic reactions like hydrogenation and carbon-carbon bond formation. It plays a key role in producing enantiomerically pure compounds, which are essential in pharmaceuticals and fine chemicals. Also employed in the development of chiral catalysts and materials for organic electronics due to its rigid and stable structure. Its applications extend to chiral stationary phases in chromatography for separating enantiomers in analytical and preparative processes.
