Chemical Structure
Description
[Hydroxy-(2,4-dinitrobenzenesulfonyloxy)iodo]benzene (CAS 389614-53-3) is a high-purity analytical reference standard with the molecular formula C12H9IN2O8S and a molecular weight of 468.18 g/mol.
[Hydroxy-(2,4-dinitrobenzenesulfonyloxy)iodo]benzene (C12H9IN2O8S) contains a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
