Chemical Structure

2-phenyl-3,4-dihydropyrimidin-4-one CAS 33643-94-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 916.68 g/mol gives 2-phenyl-3,4-dihydropyrimidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-phenyl-3,4-dihydropyrimidin-4-one (CAS 33643-94-6), molecular formula C48H32N4O8P4 and molecular weight 916.68 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-phenyl-3,4-dihydropyrimidin-4-one (C48H32N4O8P4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 35.0, corresponding to approximately 35 ring(s) or double-bond equivalent(s). With a molecular weight of 916.68 g/mol, it falls into the high-molecular-weight range. 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.

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.
