Description

Compared with other compounds in its class, the molecular weight of 692.80 g/mol gives (R)-5,5'-Decamethylenedioxy-2,2'-bis(diphenylphosphino)biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-5,5'-Decamethylenedioxy-2,2'-bis(diphenylphosphino)biphenyl (CAS 1225281-39-9), molecular formula C46H46O2P2 and molecular weight 692.80 g/mol, is a CATO reference standard with documented purity and traceability.

(R)-5,5'-Decamethylenedioxy-2,2'-bis(diphenylphosphino)biphenyl (C46H46O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
