Sodium 4-hydroxynaphthalene-2,7-disulfonate CAS 20349-39-7

Description

Compared with other compounds in its class, the molecular weight of 325.26 g/mol gives Sodium 4-hydroxynaphthalene-2,7-disulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sodium 4-hydroxynaphthalene-2,7-disulfonate (CAS 20349-39-7), a certified reference material (molecular formula C10H6O7S2Na, MW 325.26 g/mol) for analytical method development and quality control.

The molecular framework of Sodium 4-hydroxynaphthalene-2,7-disulfonate (C10H6O7S2Na) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures Sodium 4-hydroxynaphthalene-2,7-disulfonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
