Chemical Structure
Description
[2-(1,1-Dimethylethoxy)-2-oxoethyl](2-methylphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium (CAS 351531-17-4), molecular formula C43H42O2P2Pd and molecular weight 759.16 g/mol, is a CATO reference standard with documented purity and traceability.
[2-(1,1-Dimethylethoxy)-2-oxoethyl](2-methylphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium (C43H42O2P2Pd) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), [2-(1,1-Dimethylethoxy)-2-oxoethyl](2-methylphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
