Chemical Structure

Disodium Anthraquinone-2,6-disulfonate CAS 853-68-9 chemical structure

Description

As a certified reference material (CRM), Disodium Anthraquinone-2,6-disulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Disodium Anthraquinone-2,6-disulfonate (CAS 853-68-9), molecular formula C14H6O8S2Na and molecular weight 389.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Disodium Anthraquinone-2,6-disulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 389.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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