Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3,5-Dichlorophenyl)(2,4,6-trimethoxyphenyl)iodonium 4-methylbenzenesulfonate (CAS 1868173-25-4), molecular formula C15H14Cl2IO3C7H7O3S and molecular weight 611.26 g/mol, is a CATO reference standard with documented purity and traceability.
(3,5-Dichlorophenyl)(2,4,6-trimethoxyphenyl)iodonium 4-methylbenzenesulfonate (C15H14Cl2IO3C7H7O3S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (3,5-Dichlorophenyl)(2,4,6-trimethoxyphenyl)iodonium 4-methylbenzenesulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
