Chemical Structure
Description
2-{N-[5-(benzyloxy)-2,4-dichlorophenyl]4-methylbenzenesulfonamido}-N-(4-chlorophenyl)acetamide (CAS 338961-82-3), molecular formula C28H23Cl3N2O4S and molecular weight 589.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{N-[5-(benzyloxy)-2,4-dichlorophenyl]4-methylbenzenesulfonamido}-N-(4-chlorophenyl)acetamide (C28H23Cl3N2O4S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
