Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 470.06 g/mol gives 4,4'-Sulfonylbis(iodobenzene) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,4'-Sulfonylbis(iodobenzene) (CAS 40915-22-8), molecular formula C12H8I2O2S and molecular weight 470.06 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 4,4'-Sulfonylbis(iodobenzene) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 470.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4,4'-Sulfonylbis(iodobenzene) 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.
