Potassium 5,6-diaminonaphthalene-1,3-disulfonate CAS 307495-30-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium 5,6-diaminonaphthalene-1,3-disulfonate.

Potassium 5,6-diaminonaphthalene-1,3-disulfonate (CAS 307495-30-3), molecular formula C10H10N2O6S2K and molecular weight 357.42 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Potassium 5,6-diaminonaphthalene-1,3-disulfonate (C10H10N2O6S2K) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).

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

As a certified reference material (CRM), Potassium 5,6-diaminonaphthalene-1,3-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.
