Description
As a certified reference material (CRM), 207569-02-6 1,5-Naphthalenedisulfonic acid, disodium salt hydrate DTXSID0044315 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.
207569-02-6 1,5-Naphthalenedisulfonic acid, disodium salt hydrate DTXSID0044315 (CAS 207569-02-6) is a high-purity analytical reference standard with the molecular formula C10H16O6S2Na and a molecular weight of 319.34 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 207569-02-6 1,5-Naphthalenedisulfonic acid, disodium salt hydrate DTXSID0044315 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.34 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.
