Chemical Structure
Description
(S)-Diphenyl(2'-phenyl-[1,1'-binaphthalen]-2-yl)phosphine (CAS 479079-13-5) is a high-purity analytical reference standard with the molecular formula C38H27P and a molecular weight of 514.59 g/mol.
Structurally, (S)-Diphenyl(2'-phenyl-[1,1'-binaphthalen]-2-yl)phosphine (C38H27P) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 25.5, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 514.59 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
