Shanghai Ruifu Chemical Co., Ltd. is the leading manufacturer and supplier of (R)-(-)-1,1'-Binaphthyl-2,2'-diyl Hydrogen Phosphate (CAS: 39648-67-4) with high quality, it belongs to pharmaceutical intermediate and can be used for the synthesis of chiral intermediates and chiral drugs.  

Shanghai Ruifu Chemical Co., Ltd. plays an important role in the chiral chemistry, the company is committed to the production of chiral compounds. Our products are widely praised by customers. 

(R)-(-)-1,1'-Binaphthyl-2,2'-diyl Hydrogen Phosphate (CAS: 39648-67-4) is a R enantiomer of the binaphthol derivative which is used as a chiral quenching agent. It is a chiral ligand used in hydrocarboxylation reactions. Complexes with rhodium and mediates the asymmetric dipolar cycloaddition of diazo compounds. A number of racemic amines which have proven difficult to separate have been resolved with this chiral acid. Palladium derivatives have been used in asymmetric hydrocarboxylations, and rhodium derivatives have been used in dipolar cycloadditions. Used in a chiral Bronsted acid catalyzed enantoselective Mannich reaction.
