N-(3,4-dichlorobenzyl)-2-nitrobenzenesulfonamide CAS 112733-64-9

Description

The occurrence of N-(3,4-dichlorobenzyl)-2-nitrobenzenesulfonamide 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.

N-(3,4-dichlorobenzyl)-2-nitrobenzenesulfonamide (CAS 112733-64-9), molecular formula C13H10Cl2N2O4S and molecular weight 361.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H10Cl2N2O4S, N-(3,4-dichlorobenzyl)-2-nitrobenzenesulfonamide 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 361.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
