2-(4-Benzyl-3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)-6-(trifluoromethyl)-3,4-dihydropyrimidin-4-one CAS 866137-82-8

Description

Compared with other compounds in its class, the molecular weight of 350.30 g/mol gives 2-(4-Benzyl-3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)-6-(trifluoromethyl)-3,4-dihydropyrimidin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-Benzyl-3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)-6-(trifluoromethyl)-3,4-dihydropyrimidin-4-one (CAS 866137-82-8), molecular formula C16H13F3N4O2 and molecular weight 350.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-(4-Benzyl-3-methyl-5-oxo-2,5-dihydro-1H-pyrazol-1-yl)-6-(trifluoromethyl)-3,4-dihydropyrimidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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

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.
