The occurrence of 3-((4-(4-(2,4-Diaminopyrimidin-5-yl)butyl)phenyl)carbamoyl)benzene-1-sulfonyl fluoride sulfate is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-((4-(4-(2,4-Diaminopyrimidin-5-yl)butyl)phenyl)carbamoyl)benzene-1-sulfonyl fluoride sulfate (CAS 21877-93-0), a certified reference material (molecular formula C21H22FN5O3SH2O4S, MW 541.57 g/mol) for analytical method development and quality control.
3-((4-(4-(2,4-Diaminopyrimidin-5-yl)butyl)phenyl)carbamoyl)benzene-1-sulfonyl fluoride sulfate (C21H22FN5O3SH2O4S) contains a flavonoid core, 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. 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.
