Chemical Structure
Description
2-((4-Chloro-N-(4-chlorophenyl)phenyl)sulfonamido)-N-phenylacetamide (CAS 337922-00-6) is a high-purity analytical reference standard with the molecular formula C20H16Cl2N2O3S and a molecular weight of 435.32 g/mol.
2-((4-Chloro-N-(4-chlorophenyl)phenyl)sulfonamido)-N-phenylacetamide (C20H16Cl2N2O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-((4-Chloro-N-(4-chlorophenyl)phenyl)sulfonamido)-N-phenylacetamide 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.
