Chemical Structure
Description
The molecular framework of 4,4′-Carbonylbis[2-(ethoxycarbonyl)benzoic acid], 4,4′-methylenedianiline salt 1:1 (C17H10O9C13H14N2C2H6O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 4,4′-Carbonylbis[2-(ethoxycarbonyl)benzoic acid], 4,4′-methylenedianiline salt 1:1 (CAS 65701-06-6), a certified reference material (molecular formula C17H10O9C13H14N2C2H6O, MW 602.60 g/mol) for analytical method development and quality control.
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.
