Tris[(1,2-η)-1,5-diphenyl-1,4-pentadien-3-one]palladium (CAS 48243-18-1), molecular formula C51H42O3Pd and molecular weight 809.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tris[(1,2-η)-1,5-diphenyl-1,4-pentadien-3-one]palladium (C51H42O3Pd) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 31.0, corresponding to approximately 31 ring(s) or double-bond equivalent(s). With a molecular weight of 809.30 g/mol, it falls into the high-molecular-weight range. 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), Tris[(1,2-η)-1,5-diphenyl-1,4-pentadien-3-one]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.
