Chemical Structure
Description
The molecular framework of 2-((4-Chloro-N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)phenyl)sulfonamido)-N-(3-(trifluoromethyl)phenyl)acetamide (C24H20Cl3F3N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.
2-((4-Chloro-N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)phenyl)sulfonamido)-N-(3-(trifluoromethyl)phenyl)acetamide (CAS 338967-70-7), molecular formula C24H20Cl3F3N2O5S and molecular weight 611.85 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.
