7-Methylpyrido[2,3-d]pyrimidin-4(3H)-one CAS 116598-87-9

Description

Compared with other compounds in its class, the molecular weight of 161.16 g/mol gives 7-Methylpyrido[2,3-d]pyrimidin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Methylpyrido[2,3-d]pyrimidin-4(3H)-one (CAS 116598-87-9) is a high-purity analytical reference standard with the molecular formula C8H7N3O and a molecular weight of 161.16 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 7-Methylpyrido[2,3-d]pyrimidin-4(3H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.16 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.
