Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 387.43 g/mol gives N-Cyclopentyl-2-[4-(5-ethyl-1,2,4-oxadiazol-3-yl)-1,3-dioxo-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidin-2-yl]acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-Cyclopentyl-2-[4-(5-ethyl-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 1775386-86-1), molecular formula C19H25N5O4 and molecular weight 387.43 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, N-Cyclopentyl-2-[4-(5-ethyl-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 387.43 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.
