Chemical Structure
Description
The molecular framework of Palladium, dichlorobis(quinoline)-, (SP-4-1)- (C18H14Cl2N2Pd) 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.
Palladium, dichlorobis(quinoline)-, (SP-4-1)- (CAS 66514-82-7) is a high-purity analytical reference standard with the molecular formula C18H14Cl2N2Pd and a molecular weight of 435.64 g/mol.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
