2-(Ethylamino)-3-((ethylimino)methyl)-7-methyl-4H-pyrido[1,2-a]pyrimidin-4-one CAS 1785975-35-0

Description

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.

2-(Ethylamino)-3-((ethylimino)methyl)-7-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (CAS 1785975-35-0), molecular formula C14H18N4O and molecular weight 258.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-(Ethylamino)-3-((ethylimino)methyl)-7-methyl-4H-pyrido[1,2-a]pyrimidin-4-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.32 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
