Chemical Structure
Description
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 supplies Sodium 4-((4-aminophenyl)sulfonamido)-4-oxobutanoate (CAS 93777-01-6), a certified reference material (molecular formula C10H11N2O5SNa, MW 294.26 g/mol) for analytical method development and quality control.
Structurally, Sodium 4-((4-aminophenyl)sulfonamido)-4-oxobutanoate (C10H11N2O5SNa) 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 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 294.26 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).
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.
