2-(3,5-Dicarboxyphenyl)-1H-imidazole-4,5-dicarboxylic acid CAS 2181837-52-3

Description

2-(3,5-Dicarboxyphenyl)-1H-imidazole-4,5-dicarboxylic acid (CAS 2181837-52-3) is a high-purity analytical reference standard with the molecular formula C13H8N2O8 and a molecular weight of 320.21 g/mol.

The molecular framework of 2-(3,5-Dicarboxyphenyl)-1H-imidazole-4,5-dicarboxylic acid (C13H8N2O8) 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. 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.
