Description
As a certified reference material (CRM), 2-Bromo-6-ethoxy-4-formylphenyl benzenesulfonate 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.
2-Bromo-6-ethoxy-4-formylphenyl benzenesulfonate (CAS 431998-72-0), molecular formula C15H13BrO5S and molecular weight 385.23 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-6-ethoxy-4-formylphenyl benzenesulfonate (C15H13BrO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
