Description
As a certified reference material (CRM), Methyl 6-amino-5-cyano-2-(2-methoxy-2-oxoethyl)-4-(4-methoxyphenyl)-4h-pyran-3-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 6-amino-5-cyano-2-(2-methoxy-2-oxoethyl)-4-(4-methoxyphenyl)-4h-pyran-3-carboxylate (CAS 354554-29-3) is a high-purity analytical reference standard with the molecular formula C18H18N2O6 and a molecular weight of 358.35 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Methyl 6-amino-5-cyano-2-(2-methoxy-2-oxoethyl)-4-(4-methoxyphenyl)-4h-pyran-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.35 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.
