Chemical Structure
Description
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.
Bromo[[1,3-bis[(4S,5S)-1-benzoyl-4,5-diphenyl-2-imidazolin-2-yl]benzene]palladium(II)] (CAS 1242081-29-3) is a high-purity analytical reference standard with the molecular formula C50H37N4O2PdBr and a molecular weight of 912.20 g/mol.
Bromo[[1,3-bis[(4S,5S)-1-benzoyl-4,5-diphenyl-2-imidazolin-2-yl]benzene]palladium(II)] (C50H37N4O2PdBr) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
