Description

Compared with other compounds in its class, the molecular weight of 320.27 g/mol gives 5,8-Dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,8-Dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid (CAS 6483-85-8), molecular formula C14H8O7S and molecular weight 320.27 g/mol, is a CATO reference standard with documented purity and traceability.

5,8-Dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2-sulfonic acid (C14H8O7S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
