Description
Compared with other compounds in its class, the molecular weight of 235.21 g/mol gives 6-Amino-1-(4-fluorophenyl)-3-methylpyrimidine-2,4(1H,3H)-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Amino-1-(4-fluorophenyl)-3-methylpyrimidine-2,4(1H,3H)-dione (CAS 19369-30-3), a certified reference material (molecular formula C11H10FN3O2, MW 235.21 g/mol) for analytical method development and quality control.
6-Amino-1-(4-fluorophenyl)-3-methylpyrimidine-2,4(1H,3H)-dione (C11H10FN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
