3-(4-Fluoro-3-methylphenyl)-2-sulfanylidene-1H,2H,3H,4H-thieno[3,2-d]pyrimidin-4-one CAS 1255786-08-3

Description

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.

CATO supplies 3-(4-Fluoro-3-methylphenyl)-2-sulfanylidene-1H,2H,3H,4H-thieno[3,2-d]pyrimidin-4-one (CAS 1255786-08-3), a certified reference material (molecular formula C13H9FN2OS2, MW 292.35 g/mol) for analytical method development and quality control.

3-(4-Fluoro-3-methylphenyl)-2-sulfanylidene-1H,2H,3H,4H-thieno[3,2-d]pyrimidin-4-one (C13H9FN2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
