7-Hydroxynaphthalene-1,3-disulfonic acid xpotassium salt CAS 13846-08-7

Description

The occurrence of 7-Hydroxynaphthalene-1,3-disulfonic acid xpotassium salt is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Hydroxynaphthalene-1,3-disulfonic acid xpotassium salt (CAS 13846-08-7), molecular formula C10H6O7S2K and molecular weight 341.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Hydroxynaphthalene-1,3-disulfonic acid xpotassium salt (C10H6O7S2K) 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 7-Hydroxynaphthalene-1,3-disulfonic acid xpotassium salt 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.
