Description

Compared with other compounds in its class, the molecular weight of 283.13 g/mol gives 2-Chloro-n-(2-chloro-5-sulfamoylphenyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-n-(2-chloro-5-sulfamoylphenyl)acetamide (CAS 1154121-22-8) is a high-purity analytical reference standard with the molecular formula C8H8Cl2N2O3S and a molecular weight of 283.13 g/mol.

2-Chloro-n-(2-chloro-5-sulfamoylphenyl)acetamide (C8H8Cl2N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 2-Chloro-n-(2-chloro-5-sulfamoylphenyl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
