Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-3-(4-Iodophenyl)-2-(2,4-dinitrophenyl)-2H-5-tetrazolio-1,3-benzenedisulfonate sodium salt (CAS 161617-45-4), a certified reference material (molecular formula C19H12IN6O10S2Na, MW 698.35 g/mol) for analytical method development and quality control.
4-3-(4-Iodophenyl)-2-(2,4-dinitrophenyl)-2H-5-tetrazolio-1,3-benzenedisulfonate sodium salt (C19H12IN6O10S2Na) contains a salt form, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine 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.
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.
