Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-(2,4-Dinitrophenoxy)-4-methyl-2H-chromen-2-one (CAS 314742-00-2) is a high-purity analytical reference standard with the molecular formula C16H10N2O7 and a molecular weight of 342.26 g/mol.
The molecular framework of 7-(2,4-Dinitrophenoxy)-4-methyl-2H-chromen-2-one (C16H10N2O7) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 7-(2,4-Dinitrophenoxy)-4-methyl-2H-chromen-2-one 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.
