The occurrence of Sodium 2'-Hydroxyacetophenone Oxime-2-sulphinate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Sodium 2'-Hydroxyacetophenone Oxime-2-sulphinate (CAS 1024789-05-6), a certified reference material (molecular formula C8H8NO5SNa, MW 253.20 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H8NO5SNa, Sodium 2'-Hydroxyacetophenone Oxime-2-sulphinate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
