Compared with other compounds in its class, the molecular weight of 524.57 g/mol gives 2,2'-Bis[di(3,5-dimethylphenyl)phosphino]-1,1'-binaphthyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,2'-Bis[di(3,5-dimethylphenyl)phosphino]-1,1'-binaphthyl (CAS 145416-77-9), molecular formula C36H30P2 and molecular weight 524.57 g/mol, is a CATO reference standard with documented purity and traceability.
2,2'-Bis[di(3,5-dimethylphenyl)phosphino]-1,1'-binaphthyl (C36H30P2) contains organophosphorus functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
