Description
As a certified reference material (CRM), Methyl 3-(2-chlorophenyl)-5-[(1Z)-1-(dimethylamino)-4-ethoxy-3,4-dioxobut-1-en-2-yl]-1,2-oxazole-4-carboxylate 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.
Methyl 3-(2-chlorophenyl)-5-[(1Z)-1-(dimethylamino)-4-ethoxy-3,4-dioxobut-1-en-2-yl]-1,2-oxazole-4-carboxylate (CAS 1164546-60-4) is a high-purity analytical reference standard with the molecular formula C19H19ClN2O6 and a molecular weight of 406.82 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Methyl 3-(2-chlorophenyl)-5-[(1Z)-1-(dimethylamino)-4-ethoxy-3,4-dioxobut-1-en-2-yl]-1,2-oxazole-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.82 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.
