Description

S-2,2'-Dimethoxy-3,3'-Diphenyl-1,1'-Binaphthalene is a chiral binaphthyl derivative, a sophisticated organic compound of significant importance in asymmetric synthesis. Its rigid, axially chiral scaffold makes it an invaluable precursor and ligand for constructing highly selective catalysts used in pharmaceutical and fine chemical manufacturing. This product is essential for research and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity chiral auxiliaries to drive enantioselective reactions.

Application

• As a key chiral ligand precursor for asymmetric metal catalysis (e.g., hydrogenation, coupling reactions).
• Building block for the synthesis of novel organocatalysts used in enantioselective transformations.
• Intermediate in the research and development of active pharmaceutical ingredients (APIs) requiring high optical purity.
• Component in the synthesis of chiral stationary phases for analytical and preparative chromatography.
• Precursor for functional materials, such as chiral polymers and liquid crystals.
• Use in academic and industrial R&D for exploring new methodologies in asymmetric synthesis.
