Sodium 6-methoxynaphthalene-2-sulfonate CAS 149353-39-9

Description

The occurrence of Sodium 6-methoxynaphthalene-2-sulfonate 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.

Sodium 6-methoxynaphthalene-2-sulfonate (CAS 149353-39-9), molecular formula C11H9NaO4S and molecular weight 260.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Sodium 6-methoxynaphthalene-2-sulfonate (C11H9NaO4S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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 6-methoxynaphthalene-2-sulfonate 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.
