Used as a chiral ligand in asymmetric synthesis, particularly in catalytic reactions where enantioselectivity is crucial. It is often employed in the formation of carbon-carbon bonds, such as in asymmetric hydrogenation or addition reactions. Its rigid structure and ability to coordinate with metals make it valuable in producing enantiomerically pure compounds, which are essential in pharmaceuticals and fine chemicals. Additionally, it can serve as a building block in the synthesis of more complex chiral molecules.
