Used as a chiral ligand in asymmetric synthesis, particularly in catalytic reactions where enantioselectivity is crucial. It is applied in the production of pharmaceuticals, agrochemicals, and fine chemicals, enabling the synthesis of complex molecules with high optical purity. Its binaphthalene structure provides a rigid framework that enhances control over stereochemistry in metal-catalyzed processes, such as hydrogenation, cross-coupling, and cyclization reactions. This chemical is also employed in the development of advanced materials and sensors due to its ability to induce chirality in molecular assemblies. Its dichloro and diethoxy substituents further tune its electronic properties, making it versatile for diverse catalytic applications.
