Chemical Structure

2-Chloro-n-(4-chlorophenyl)-5-nitrobenzene-1-sulfonamide CAS 380342-48-3 chemical structure

Description

The occurrence of 2-Chloro-n-(4-chlorophenyl)-5-nitrobenzene-1-sulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Chloro-n-(4-chlorophenyl)-5-nitrobenzene-1-sulfonamide (CAS 380342-48-3) is a high-purity analytical reference standard with the molecular formula C12H8Cl2N2O4S and a molecular weight of 347.17 g/mol.

Based on its molecular formula C12H8Cl2N2O4S, 2-Chloro-n-(4-chlorophenyl)-5-nitrobenzene-1-sulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 347.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
