[4,4'-Bipyridine]-2,2',6,6'-tetracarboxylic acid CAS 124558-60-7

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.

[4,4'-Bipyridine]-2,2',6,6'-tetracarboxylic acid (CAS 124558-60-7) is a high-purity analytical reference standard with the molecular formula C14H8N2O8 and a molecular weight of 332.22 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, [4,4'-Bipyridine]-2,2',6,6'-tetracarboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
