Description

Compared with other compounds in its class, the molecular weight of 366.36 g/mol gives 4-((4-(N-(4-fluorophenyl)sulfamoyl)phenyl)amino)-4-oxobutanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-((4-(N-(4-fluorophenyl)sulfamoyl)phenyl)amino)-4-oxobutanoic acid (CAS 383-43-7), a certified reference material (molecular formula C16H15FN2O5S, MW 366.36 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H15FN2O5S, 4-((4-(N-(4-fluorophenyl)sulfamoyl)phenyl)amino)-4-oxobutanoic acid contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 366.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
