Chemical Structure
Description
2-((5,7-Dimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)thio)-1-(5-fluoro-2-methoxyphenyl)ethan-1-one (C16H15FN4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. 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).
CATO supplies 2-((5,7-Dimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl)thio)-1-(5-fluoro-2-methoxyphenyl)ethan-1-one (CAS 871797-45-4), a certified reference material (molecular formula C16H15FN4O2S, MW 346.38 g/mol) for analytical method development and quality control.
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.
