5-Chloro-N-(4-sulfamoylphenyl)thiophene-2-carboxamide CAS 306738-77-2

Description

5-Chloro-N-(4-sulfamoylphenyl)thiophene-2-carboxamide (CAS 306738-77-2) is a high-purity analytical reference standard with the molecular formula C11H9ClN2O3S2 and a molecular weight of 316.78 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 5-Chloro-N-(4-sulfamoylphenyl)thiophene-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 5-Chloro-N-(4-sulfamoylphenyl)thiophene-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.
