Chemical Structure
Description
Diacetate{2,2'-bis(diphenylphosphino)-1,1'-binaphthyl}palladium(II) (CAS 331749-09-8), molecular formula C48H38O4P2Pd and molecular weight 847.18 g/mol, is a CATO reference standard with documented purity and traceability.
Diacetate{2,2'-bis(diphenylphosphino)-1,1'-binaphthyl}palladium(II) (C48H38O4P2Pd) contains a phosphate ester group, 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 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.
