2-((N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)-4-methoxyphenyl)sulfonamido)-N-(4-fluorophenyl)acetamide CAS 338967-85-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 557.42 g/mol gives 2-((N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)-4-methoxyphenyl)sulfonamido)-N-(4-fluorophenyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-((N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)-4-methoxyphenyl)sulfonamido)-N-(4-fluorophenyl)acetamide (CAS 338967-85-4), a certified reference material (molecular formula C24H23Cl2FN2O6S, MW 557.42 g/mol) for analytical method development and quality control.

2-((N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)-4-methoxyphenyl)sulfonamido)-N-(4-fluorophenyl)acetamide (C24H23Cl2FN2O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
