Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1'-[(1Z)-1-(1,1-Dimethylethyl)-1,2-ethenediyl]bis[1,1-diphenylphosphine] (CAS 66493-16-1), molecular formula C30H30P2 and molecular weight 452.51 g/mol, is a CATO reference standard with documented purity and traceability.
1,1'-[(1Z)-1-(1,1-Dimethylethyl)-1,2-ethenediyl]bis[1,1-diphenylphosphine] (C30H30P2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
