The occurrence of 9-Methyl-2-phenyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
9-Methyl-2-phenyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidin-4-one (CAS 58554-02-2), molecular formula C15H16N2O and molecular weight 240.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H16N2O, 9-Methyl-2-phenyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidin-4-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 9-Methyl-2-phenyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidin-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
