Description
As a certified reference material (CRM), 4-(2,4-Dinitrophenoxy)-3-ethoxy-5-iodobenzaldehyde 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.
CATO supplies 4-(2,4-Dinitrophenoxy)-3-ethoxy-5-iodobenzaldehyde (CAS 792945-74-5), a certified reference material (molecular formula C15H11IN2O7, MW 458.16 g/mol) for analytical method development and quality control.
4-(2,4-Dinitrophenoxy)-3-ethoxy-5-iodobenzaldehyde (C15H11IN2O7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
