Description

R-3,3'-Bis(4-Nitrophenyl)-5,5',6,6',7,7',8,8'-Octahydro-1,1'-Binaphthyl-2,2'-Diyl Hydrogenphosphate is a sophisticated chiral organophosphate compound that serves as a critical intermediate and ligand in advanced synthetic chemistry. Its value lies in its unique binaphthyl backbone, which provides a rigid, three-dimensional framework essential for inducing high stereoselectivity in catalytic reactions. This product is primarily needed by research institutions and pharmaceutical companies engaged in the development of novel asymmetric catalysts, chiral auxiliaries, and active pharmaceutical ingredients (APIs).

Application

• As a chiral ligand in asymmetric metal-catalyzed reactions, including hydrogenation and cross-coupling.
• As a key intermediate in the synthesis of complex pharmaceutical molecules requiring high enantiomeric purity.
• In the research and development of novel organocatalysts for green and sustainable chemistry applications.
• For the preparation of chiral stationary phases (CSPs) used in high-performance liquid chromatography (HPLC) for enantiomer separation.
• In material science research for developing chiral polymers and advanced functional materials.
• As a reference standard in analytical method development and quality control laboratories.
