Compared with other compounds in its class, the molecular weight of 493.73 g/mol gives Palladium, dichlorobis[1-(phenylmethyl)-1H-imidazole-κN3]-, (SP-4-1)- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Palladium, dichlorobis[1-(phenylmethyl)-1H-imidazole-κN3]-, (SP-4-1)- (CAS 944538-72-1), molecular formula C20H20Cl2N4Pd and molecular weight 493.73 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Palladium, dichlorobis[1-(phenylmethyl)-1H-imidazole-κN3]-, (SP-4-1)- (C20H20Cl2N4Pd) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Palladium, dichlorobis[1-(phenylmethyl)-1H-imidazole-κN3]-, (SP-4-1)- 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.
