CATO supplies N-(2-((3-(3-Fluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)ethyl)-3,5-dimethylisoxazole-4-sulfonamide (CAS 1203415-31-9), a certified reference material (molecular formula C18H17FN6O4S, MW 432.43 g/mol) for analytical method development and quality control.
N-(2-((3-(3-Fluorophenyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)oxy)ethyl)-3,5-dimethylisoxazole-4-sulfonamide (C18H17FN6O4S) 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.
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.
