As a certified reference material (CRM), 3-Hydroxy-2-(((4-methoxy-2-nitrophenyl)imino)methyl)-5,5-dimethylcyclohex-2-en-1-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.
3-Hydroxy-2-(((4-methoxy-2-nitrophenyl)imino)methyl)-5,5-dimethylcyclohex-2-en-1-one (CAS 202459-41-4) is a high-purity analytical reference standard with the molecular formula C16H18N2O5 and a molecular weight of 318.32 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 3-Hydroxy-2-(((4-methoxy-2-nitrophenyl)imino)methyl)-5,5-dimethylcyclohex-2-en-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
