3-bromo-4-(2,4-dinitrophenoxy)-5-methoxybenzaldehyde CAS 591240-92-5

Description

3-bromo-4-(2,4-dinitrophenoxy)-5-methoxybenzaldehyde (CAS 591240-92-5), molecular formula C14H9BrN2O7 and molecular weight 397.13 g/mol, is a CATO reference standard with documented purity and traceability.

3-bromo-4-(2,4-dinitrophenoxy)-5-methoxybenzaldehyde (C14H9BrN2O7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.

As a certified reference material (CRM), 3-bromo-4-(2,4-dinitrophenoxy)-5-methoxybenzaldehyde 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.
