Description
As a certified reference material (CRM), [4-(Bromomethyl)phenyl](2,4,6-trimethoxyphenyl)iodonium p-Toluenesulfonate 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.
[4-(Bromomethyl)phenyl](2,4,6-trimethoxyphenyl)iodonium p-Toluenesulfonate (CAS 1453864-75-9) is a high-purity analytical reference standard with the molecular formula C16H17BrIO3C7H7O3S and a molecular weight of 635.30 g/mol.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine/iodine substitution, [4-(Bromomethyl)phenyl](2,4,6-trimethoxyphenyl)iodonium p-Toluenesulfonate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 635.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
