Chemical Structure
Description
722-56-5 A837466 bis(oxidanyl)-oxidanylidene-azanium; diphenyliodanium dihydroxy(oxo)ammonium; diphenyliodonium (C12H22INO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
722-56-5 A837466 bis(oxidanyl)-oxidanylidene-azanium; diphenyliodanium dihydroxy(oxo)ammonium; diphenyliodonium (CAS 722-56-5) is a high-purity analytical reference standard with the molecular formula C12H22INO3 and a molecular weight of 355.21 g/mol.
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.
