Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 600.06 g/mol gives Bis(4-bromophenyl)iodonium triflate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Bis(4-bromophenyl)iodonium triflate (CAS 139139-81-4), a certified reference material (molecular formula C12H20Br2ICF3O3S, MW 600.06 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, Bis(4-bromophenyl)iodonium triflate is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 600.06 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), Bis(4-bromophenyl)iodonium triflate 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.
