Chemical Structure
Description
As a certified reference material (CRM), Sodium 3-iodobenzenesulfonate 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.
CATO supplies Sodium 3-iodobenzenesulfonate (CAS 51119-76-7), a certified reference material (molecular formula C6H4IO3SNa, MW 306.05 g/mol) for analytical method development and quality control.
Structurally, Sodium 3-iodobenzenesulfonate (C6H4IO3SNa) contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 306.05 g/mol, it falls into the moderately-high-molecular-weight range. 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.
