(R)-(-)-3,3′-Bis(triphenylsilyl)-1,1′-bi, naphthyl-2,2′-diyl hydrogenphosphate

(R)-(-)-3,3′-Bis(triphenylsilyl)-1,1′-binaphthyl-2,2′-diyl hydrogenphosphate is a sterically demanding chiral binaphthyl phosphoric acid derivative for advanced organic and biochemical synthesis. It is characterised by the empirical formula C₅₆H₄₁O₄PSi₂, a molar mass of 865,07 g/mol and CAS number 791616-55-2. The 3,3′-bis(triphenylsilyl) substitution on the binaphthyl backbone creates a highly hindered chiral environment around the hydrogenphosphate moiety, making the compound relevant for enantioselective transformations and catalyst or ligand development. This grade is offered in a 2,5 g pack size appropriate for method scouting and small-scale preparative work. Available from manufacturer Carl ROTH, the reagent fits research programmes in asymmetric catalysis, organocatalysis and stereocontrolled C–C or C–heteroatom bond formation. Clear structural and mass data support documentation in experimental sections and regulatory filings. Handle as a specialised fine chemical under standard laboratory safety procedures when weighing and dissolving the material for catalytic or stoichiometric applications.
