Description

Compared with other compounds in its class, the molecular weight of 420.42 g/mol gives 4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-({4-oxo-4H-pyrido[1,2-a]pyrimidin-2-yl}methyl)-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidine-1,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-({4-oxo-4H-pyrido[1,2-a]pyrimidin-2-yl}methyl)-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidine-1,3-dione (CAS 1775353-81-5) is a high-purity analytical reference standard with the molecular formula C21H20N6O4 and a molecular weight of 420.42 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-({4-oxo-4H-pyrido[1,2-a]pyrimidin-2-yl}methyl)-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidine-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.42 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
