(R)-(-)-1,1’-Binaphthyl-2,2’-diyl Hydrogen Phosphate(CAT: R009670) is a chiral organophosphoric acid derivative widely employed as a resolving agent and chiral ligand in asymmetric synthesis. Featuring an axially chiral binaphthyl backbone, it provides excellent stereocontrol in catalytic reactions, particularly in metal-catalyzed asymmetric transformations such as hydrogenations, allylic substitutions, and cycloadditions. Its rigid, stereodefined structure makes it a key building block in the preparation of chiral phosphoric acid catalysts for enantioselective reactions. Soluble in a range of organic solvents, it is favored in fine chemical and pharmaceutical research for producing high-purity enantiomers with exceptional selectivity and yield.
