N-(Quinoxalin-2-ylmethyl)-N-(4-sulfamoylphenyl)formamide CAS 62294-94-4

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 N-(Quinoxalin-2-ylmethyl)-N-(4-sulfamoylphenyl)formamide (CAS 62294-94-4), a certified reference material (molecular formula C16H14N4O3S, MW 342.37 g/mol) for analytical method development and quality control.

Structurally, N-(Quinoxalin-2-ylmethyl)-N-(4-sulfamoylphenyl)formamide (C16H14N4O3S) 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 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 342.37 g/mol, it falls into the moderately-high-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.
