Description

Compared with other compounds in its class, the molecular weight of 800.66 g/mol gives 1,2,4,5-Benzenetetracarboxylic acid, 1,4-dimethyl ester, polymer with 1,5-dimethyl dihydrogen 1,2,4,5-benzenetetracarboxylate and 4,4'-[[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]bis(4,1-phenyleneoxy)]bis[benzenamine] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,2,4,5-Benzenetetracarboxylic acid, 1,4-dimethyl ester, polymer with 1,5-dimethyl dihydrogen 1,2,4,5-benzenetetracarboxylate and 4,4'-[[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]bis(4,1-phenyleneoxy)]bis[benzenamine] (CAS 125304-20-3), a certified reference material (molecular formula C27H20F6N2O2C12H10O8, MW 800.66 g/mol) for analytical method development and quality control.

The molecular framework of 1,2,4,5-Benzenetetracarboxylic acid, 1,4-dimethyl ester, polymer with 1,5-dimethyl dihydrogen 1,2,4,5-benzenetetracarboxylate and 4,4'-[[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]bis(4,1-phenyleneoxy)]bis[benzenamine] (C27H20F6N2O2C12H10O8) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.

As a certified reference material (CRM), 1,2,4,5-Benzenetetracarboxylic acid, 1,4-dimethyl ester, polymer with 1,5-dimethyl dihydrogen 1,2,4,5-benzenetetracarboxylate and 4,4'-[[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]bis(4,1-phenyleneoxy)]bis[benzenamine] meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
