Compared with other compounds in its class, the molecular weight of 552.60 g/mol gives (4S,4'S)-2,2'-((Phenylphosphinediyl)bis(2,1-phenylene))bis(4-phenyl-4,5-dihydrooxazole) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4S,4'S)-2,2'-((Phenylphosphinediyl)bis(2,1-phenylene))bis(4-phenyl-4,5-dihydrooxazole) (CAS 2368937-53-3), molecular formula C36H29N2O2P and molecular weight 552.60 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4S,4'S)-2,2'-((Phenylphosphinediyl)bis(2,1-phenylene))bis(4-phenyl-4,5-dihydrooxazole) (C36H29N2O2P) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 23.5, corresponding to approximately 23 ring(s) or double-bond equivalent(s). With a molecular weight of 552.60 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
