Description
Compared with other compounds in its class, the molecular weight of 664.75 g/mol gives (S)-5,5'-Octamethylenedioxy-2,2'-bis(diphenylphosphino)biphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-5,5'-Octamethylenedioxy-2,2'-bis(diphenylphosphino)biphenyl (CAS 1217339-62-2), molecular formula C44H42O2P2 and molecular weight 664.75 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-5,5'-Octamethylenedioxy-2,2'-bis(diphenylphosphino)biphenyl (C44H42O2P2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
