Description
N-(2-Methoxyphenyl)-2-[4-(5-methyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide (CAS 1775402-73-7) is a high-purity analytical reference standard with the molecular formula C20H21N5O5 and a molecular weight of 411.41 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, N-(2-Methoxyphenyl)-2-[4-(5-methyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 411.41 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.
As a certified reference material (CRM), N-(2-Methoxyphenyl)-2-[4-(5-methyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide 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.
