Chemical Structure

Ammonium 1,4-dioxo-1,4-dihydronaphthalene-2-sulfonate CAS 56633-19-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 255.24 g/mol gives Ammonium 1,4-dioxo-1,4-dihydronaphthalene-2-sulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ammonium 1,4-dioxo-1,4-dihydronaphthalene-2-sulfonate (CAS 56633-19-3), a certified reference material (molecular formula C10H5O5SH4N, MW 255.24 g/mol) for analytical method development and quality control.

Structurally, Ammonium 1,4-dioxo-1,4-dihydronaphthalene-2-sulfonate (C10H5O5SH4N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 255.24 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
