Compared with other compounds in its class, the molecular weight of 389.30 g/mol gives Sodium 9,10-dioxo-9,10-dihydroanthracene-1,7-disulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sodium 9,10-dioxo-9,10-dihydroanthracene-1,7-disulfonate (CAS 68213-99-0) is a high-purity analytical reference standard with the molecular formula C14H6O8S2Na and a molecular weight of 389.30 g/mol.
The molecular framework of Sodium 9,10-dioxo-9,10-dihydroanthracene-1,7-disulfonate (C14H6O8S2Na) is characterized by a sulfone group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
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.
