2,2'-(((Oxalylbis(4,1-phenylene))bis(oxy))bis(4,1-phenylene))bis(1-phenylethane-1,2-dione) CAS 59727-31-0

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.

CATO supplies 2,2'-(((Oxalylbis(4,1-phenylene))bis(oxy))bis(4,1-phenylene))bis(1-phenylethane-1,2-dione) (CAS 59727-31-0), a certified reference material (molecular formula C42H26O8, MW 658.65 g/mol) for analytical method development and quality control.

The molecular framework of 2,2'-(((Oxalylbis(4,1-phenylene))bis(oxy))bis(4,1-phenylene))bis(1-phenylethane-1,2-dione) (C42H26O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).

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.
