Chemical Structure
Description
The molecular framework of 1-(2-Chloro-4-nitrophenyl)-N-(phenylsulfamoyl)-1H-pyrrole-2-carboxamide (C17H13ClN4O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
1-(2-Chloro-4-nitrophenyl)-N-(phenylsulfamoyl)-1H-pyrrole-2-carboxamide (CAS 383147-37-3), molecular formula C17H13ClN4O5S and molecular weight 420.83 g/mol, is a CATO reference standard with documented purity and traceability.
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), 1-(2-Chloro-4-nitrophenyl)-N-(phenylsulfamoyl)-1H-pyrrole-2-carboxamide 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.
