4-((4-((4-(2,5-Dimethyl-1H-pyrrol-1-yl)phenyl)sulfonyl)phenyl)amino)-4-oxobutanoic acid CAS 5414-55-1

Description

Compared with other compounds in its class, the molecular weight of 426.49 g/mol gives 4-((4-((4-(2,5-Dimethyl-1H-pyrrol-1-yl)phenyl)sulfonyl)phenyl)amino)-4-oxobutanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-((4-((4-(2,5-Dimethyl-1H-pyrrol-1-yl)phenyl)sulfonyl)phenyl)amino)-4-oxobutanoic acid (CAS 5414-55-1), molecular formula C22H22N2O5S and molecular weight 426.49 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-((4-((4-(2,5-Dimethyl-1H-pyrrol-1-yl)phenyl)sulfonyl)phenyl)amino)-4-oxobutanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 426.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 4-((4-((4-(2,5-Dimethyl-1H-pyrrol-1-yl)phenyl)sulfonyl)phenyl)amino)-4-oxobutanoic acid 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.
