Chemical Structure
Description
The occurrence of Di-4-chlorophenyl iodonium bromide is closely related to chlorine/bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Di-4-chlorophenyl iodonium bromide (CAS 26018-88-2), molecular formula C12H8Cl2IBr and molecular weight 429.90 g/mol, is a CATO reference standard with documented purity and traceability.
Di-4-chlorophenyl iodonium bromide (C12H8Cl2IBr) contains chlorine/bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Di-4-chlorophenyl iodonium bromide 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.
