Description
[1-Butyl-1,3-dihydro-3-[(3-methoxyphenyl)methyl]-2H-benzimidazol-2-ylidene]dichloro(pyridine)palladium (CAS 2304464-52-4), molecular formula C24H28Cl2N3OPd and molecular weight 551.82 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, [1-Butyl-1,3-dihydro-3-[(3-methoxyphenyl)methyl]-2H-benzimidazol-2-ylidene]dichloro(pyridine)palladium (C24H28Cl2N3OPd) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.5, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 551.82 g/mol, it falls into the moderately-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), [1-Butyl-1,3-dihydro-3-[(3-methoxyphenyl)methyl]-2H-benzimidazol-2-ylidene]dichloro(pyridine)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.
