Chemical Structure
Description
As a certified reference material (CRM), 2-Iodobenzenesulfonic Acid Dihydrate 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.
2-Iodobenzenesulfonic Acid Dihydrate (CAS 1094026-90-0), molecular formula C6H5IO3SH2O and molecular weight 302.08 g/mol, is a CATO reference standard with documented purity and traceability.
2-Iodobenzenesulfonic Acid Dihydrate (C6H5IO3SH2O) contains a sulfone 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, 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.
