Description

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.

[[3,6-Dimethoxy-2′,4′,6′-tris(1-methylethyl)[1,1′-biphenyl]-2-yl]bis(1,1-dimethylethyl)phosphine-κP](methanesulfonato-κO)[2′-(methylamino-κN)[1,1′-biphenyl]-2-yl-κC]palladium (CAS 1980785-05-4) is a high-purity analytical reference standard with the molecular formula C45H64NO5PPdS and a molecular weight of 868.45 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, [[3,6-Dimethoxy-2′,4′,6′-tris(1-methylethyl)[1,1′-biphenyl]-2-yl]bis(1,1-dimethylethyl)phosphine-κP](methanesulfonato-κO)[2′-(methylamino-κN)[1,1′-biphenyl]-2-yl-κC]palladium is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 868.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
