[2-[4-(1,1-Dimethylethyl)phenyl]-2-oxoethyl](4-methoxyphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium (CAS 727722-27-2), molecular formula C49H46O2P2Pd and molecular weight 835.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [2-[4-(1,1-Dimethylethyl)phenyl]-2-oxoethyl](4-methoxyphenyl)[1,2-phenylenebis[diphenylphosphine-κP]]palladium (C49H46O2P2Pd) is characterized by organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-[4-(1,1-Dimethylethyl)phenyl]-2-oxoethyl](4-methoxyphenyl)[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.
