6-Methylpyrimidin-4(1H)-one CAS 156647-95-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

6-Methylpyrimidin-4(1H)-one (CAS 156647-95-9) is a high-purity analytical reference standard with the molecular formula C5H6N2O and a molecular weight of 110.11 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 6-Methylpyrimidin-4(1H)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 110.11 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).

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.
