Compared with other compounds in its class, the molecular weight of 360.17 g/mol gives 4-Iodophenylphenylsulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Iodophenylphenylsulfonate (CAS 408336-17-4) is a high-purity analytical reference standard with the molecular formula C12H9IO3S and a molecular weight of 360.17 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 4-Iodophenylphenylsulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 4-Iodophenylphenylsulfonate 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.
