Chemical Structure
Description
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.
CATO supplies Potassium 4-iodo-2-sulfonatobenzoate (CAS 619297-89-1), a certified reference material (molecular formula C7H3IO5SK, MW 365.15 g/mol) for analytical method development and quality control.
Potassium 4-iodo-2-sulfonatobenzoate (C7H3IO5SK) contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. 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.
