Description

Compared with other compounds in its class, the molecular weight of 284.37 g/mol gives 1,4-dioxonaphthalene-2-sulfonic acid;potassium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,4-dioxonaphthalene-2-sulfonic acid;potassium salt (CAS 34169-62-5), molecular formula C10H12O5SHK and molecular weight 284.37 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,4-dioxonaphthalene-2-sulfonic acid;potassium salt (C10H12O5SHK) 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 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.
