Description
As a certified reference material (CRM), 3-Iodo-5-methoxybenzenesulfonyl chloride 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.
3-Iodo-5-methoxybenzenesulfonyl chloride (CAS 1393584-09-2), molecular formula C7H6ClIO3S and molecular weight 332.54 g/mol, is a CATO reference standard with documented purity and traceability.
3-Iodo-5-methoxybenzenesulfonyl chloride (C7H6ClIO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
