Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R)-1,1'-(5,5',6,6',7,7',8,8'-Octahydro[2,2'-binaphthalene]-3,3'-diyl)bis[1,1-diphenylphosphine].
(2R)-1,1'-(5,5',6,6',7,7',8,8'-Octahydro[2,2'-binaphthalene]-3,3'-diyl)bis[1,1-diphenylphosphine] (CAS 1067889-87-5) is a high-purity analytical reference standard with the molecular formula C44H40P2 and a molecular weight of 630.74 g/mol.
Structurally, (2R)-1,1'-(5,5',6,6',7,7',8,8'-Octahydro[2,2'-binaphthalene]-3,3'-diyl)bis[1,1-diphenylphosphine] (C44H40P2) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 25.0, corresponding to approximately 25 ring(s) or double-bond equivalent(s). With a molecular weight of 630.74 g/mol, it falls into the 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
