Description

Compared with other compounds in its class, the molecular weight of 222.24 g/mol gives 6-(3-Fluorophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-(3-Fluorophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 33297-99-3), molecular formula C10H7FN2OS and molecular weight 222.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 6-(3-Fluorophenyl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.24 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.

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.
