6-ethyl-2-(pyridin-4-yl)-3,4-dihydropyrimidin-4-one CAS 1146290-21-2

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.

6-ethyl-2-(pyridin-4-yl)-3,4-dihydropyrimidin-4-one (CAS 1146290-21-2) is a high-purity analytical reference standard with the molecular formula C11H11N3O and a molecular weight of 201.22 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 6-ethyl-2-(pyridin-4-yl)-3,4-dihydropyrimidin-4-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 201.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
