(R)-(2,2',6,6'-Tetramethoxy-[3,3'-bipyridine]-4,4'-diyl)bis(bis(3,5-dimethylphenyl)phosphine oxide) CAS 442905-30-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 788.85 g/mol gives (R)-(2,2',6,6'-Tetramethoxy-[3,3'-bipyridine]-4,4'-diyl)bis(bis(3,5-dimethylphenyl)phosphine oxide) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-(2,2',6,6'-Tetramethoxy-[3,3'-bipyridine]-4,4'-diyl)bis(bis(3,5-dimethylphenyl)phosphine oxide) (CAS 442905-30-8) is a high-purity analytical reference standard with the molecular formula C46H50N2O6P2 and a molecular weight of 788.85 g/mol.

The molecular framework of (R)-(2,2',6,6'-Tetramethoxy-[3,3'-bipyridine]-4,4'-diyl)bis(bis(3,5-dimethylphenyl)phosphine oxide) (C46H50N2O6P2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
