Chemical Structure
Description
The occurrence of 2-((4-Chloro-N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)phenyl)sulfonamido)-N-methylacetamide is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-((4-Chloro-N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)phenyl)sulfonamido)-N-methylacetamide (CAS 338967-67-2), a certified reference material (molecular formula C18H19Cl3N2O5S, MW 481.78 g/mol) for analytical method development and quality control.
2-((4-Chloro-N-(2,4-dichloro-5-(2-methoxyethoxy)phenyl)phenyl)sulfonamido)-N-methylacetamide (C18H19Cl3N2O5S) contains a flavonoid 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.
