Description

S-3,3'-Bis(Phenyl)-1,1'-Bi-2-Naphthol is a high-purity, chiral binaphthol derivative widely recognized as a versatile and effective ligand and catalyst precursor in asymmetric synthesis. Its value lies in its ability to induce high enantioselectivity in a range of critical organic transformations, enabling the production of single-enantiomer compounds. This product is essential for research and development chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries who require reliable, high-performance chiral auxiliaries for creating optically active intermediates and active ingredients.

Application

• As a chiral ligand for asymmetric metal-catalyzed reactions, including hydrogenation, Diels-Alder, and aldol additions.
• As a precursor for constructing chiral phosphoric acid catalysts used in organocatalysis.
• In the synthesis of enantiomerically pure pharmaceutical intermediates, such as those for cardiovascular and central nervous system drugs.
• For the development of novel chiral materials and polymers with specific optical properties.
• In academic and industrial R&D for methodological development in stereoselective synthesis.
• As a resolving agent or chiral selector in chromatographic separations.
