Chemical Structure

N-Methyl-4-nitrobenzenesulfonamide CAS 6319-45-5 chemical structure

Description

Structurally, N-Methyl-4-nitrobenzenesulfonamide (C7H8N2O4S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 216.21 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).

N-Methyl-4-nitrobenzenesulfonamide (CAS 6319-45-5) is a high-purity analytical reference standard with the molecular formula C7H8N2O4S and a molecular weight of 216.21 g/mol.

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.
