Used as a building block in organic synthesis, particularly in the preparation of chiral ligands and catalysts for asymmetric reactions. Its rigid binaphthyl backbone provides structural stability and stereochemical control, making it valuable in the development of enantioselective catalytic systems. Commonly employed in the synthesis of advanced materials and functionalized polymers due to the reactivity of the nitrile groups, which can be transformed into carboxylic acids, amines, or heterocycles. Also explored in supramolecular chemistry for designing molecular receptors and sensors.
