Chemical Structure
Description
CATO supplies Sodium 3-amino-4-hydroxy-5-nitrobenzenesulfonate (CAS 85204-14-4), a certified reference material (molecular formula C6H5N2O6SNa, MW 256.16 g/mol) for analytical method development and quality control.
Structurally, Sodium 3-amino-4-hydroxy-5-nitrobenzenesulfonate (C6H5N2O6SNa) contains a carbohydrate-derived structure, an amide group, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 256.16 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.
