Chemical Structure

9-Methyl-4-oxo-2-thiomorpholino-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde CAS 489401-12-9 chemical structure

Description

The molecular framework of 9-Methyl-4-oxo-2-thiomorpholino-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde (C14H15N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

9-Methyl-4-oxo-2-thiomorpholino-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde (CAS 489401-12-9) is a high-purity analytical reference standard with the molecular formula C14H15N3O2S and a molecular weight of 289.35 g/mol.
