Description
Potassium 2,2'-((2-(2-(2-(bis(carboxylatomethyl)amino)-5-(2,7-dichloro-6-oxido-3-oxo-3H-xanthen-9-yl)phenoxy)ethoxy)-4-methylphenyl)azanediyl)diacetate (CAS 853400-67-6), molecular formula C36H25Cl2N2O13K and molecular weight 803.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Potassium 2,2'-((2-(2-(2-(bis(carboxylatomethyl)amino)-5-(2,7-dichloro-6-oxido-3-oxo-3H-xanthen-9-yl)phenoxy)ethoxy)-4-methylphenyl)azanediyl)diacetate (C36H25Cl2N2O13K) is characterized by a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
