3-((3,5-Dichlorophenyl)sulfonyl)-2-hydroxy-2-methyl-N-(4-(trifluoromethyl)phenyl)propanamide (CAS 338956-21-1) is a high-purity analytical reference standard with the molecular formula C17H14Cl2F3NO4S and a molecular weight of 456.26 g/mol.
The molecular framework of 3-((3,5-Dichlorophenyl)sulfonyl)-2-hydroxy-2-methyl-N-(4-(trifluoromethyl)phenyl)propanamide (C17H14Cl2F3NO4S) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 3-((3,5-Dichlorophenyl)sulfonyl)-2-hydroxy-2-methyl-N-(4-(trifluoromethyl)phenyl)propanamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
