Chemical Structure
Description
The molecular framework of 4-((4-(N-(3,4-dimethylphenyl)sulfamoyl)phenyl)amino)-4-oxobutanoic acid (C18H20N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
4-((4-(N-(3,4-dimethylphenyl)sulfamoyl)phenyl)amino)-4-oxobutanoic acid (CAS 606924-87-2), molecular formula C18H20N2O5S and molecular weight 376.43 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
