2,2'-((9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(azanediyl))dibenzoic acid CAS 81-78-7

Description

The occurrence of 2,2'-((9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(azanediyl))dibenzoic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2'-((9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(azanediyl))dibenzoic acid (CAS 81-78-7) is a high-purity analytical reference standard with the molecular formula C28H18N2O6 and a molecular weight of 478.45 g/mol.

The molecular framework of 2,2'-((9,10-Dioxo-9,10-dihydroanthracene-1,5-diyl)bis(azanediyl))dibenzoic acid (C28H18N2O6) is characterized by a steroid core, 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).

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.
