4-Methyl-2H-pyrido[1,2-a]pyrimidin-2-one CAS 35549-22-5

Description

Compared with other compounds in its class, the molecular weight of 160.17 g/mol gives 4-Methyl-2H-pyrido[1,2-a]pyrimidin-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Methyl-2H-pyrido[1,2-a]pyrimidin-2-one (CAS 35549-22-5) is a high-purity analytical reference standard with the molecular formula C9H8N2O and a molecular weight of 160.17 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Methyl-2H-pyrido[1,2-a]pyrimidin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
