Chemical Structure
Description
(E)-3-(4,5-dimethoxy-2-nitrophenyl)-N-(4-fluorophenyl)acrylamide (C17H15FN2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
(E)-3-(4,5-dimethoxy-2-nitrophenyl)-N-(4-fluorophenyl)acrylamide (CAS 331461-79-1), molecular formula C17H15FN2O5 and molecular weight 346.31 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (E)-3-(4,5-dimethoxy-2-nitrophenyl)-N-(4-fluorophenyl)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.
