(S)-2,2'-Bis(dicyclohexylphosphino)-5,5',6,6',7,7',8,8'-octahydro-1,1'-binaphthalene CAS 139139-94-9

Description

Owing to organophosphorus functionality, a polycyclic aromatic system, (S)-2,2'-Bis(dicyclohexylphosphino)-5,5',6,6',7,7',8,8'-octahydro-1,1'-binaphthalene is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 654.93 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(S)-2,2'-Bis(dicyclohexylphosphino)-5,5',6,6',7,7',8,8'-octahydro-1,1'-binaphthalene (CAS 139139-94-9), molecular formula C44H64P2 and molecular weight 654.93 g/mol, is a CATO reference standard with documented purity and traceability.
