Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 259.13 g/mol gives (E)-N-(2,4-dichlorophenyl)-3-(dimethylamino)acrylamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-N-(2,4-dichlorophenyl)-3-(dimethylamino)acrylamide (CAS 338976-57-1), molecular formula C11H12Cl2N2O and molecular weight 259.13 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-N-(2,4-dichlorophenyl)-3-(dimethylamino)acrylamide (C11H12Cl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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), (E)-N-(2,4-dichlorophenyl)-3-(dimethylamino)acrylamide 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.
