Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,4-dichlorophenyl 4,5,6,7-tetrafluoro-2-methylbenzo[b]furan-3-sulphonate (CAS 256329-74-5) is a high-purity analytical reference standard with the molecular formula C15H6Cl2F4O4S and a molecular weight of 429.17 g/mol.
2,4-dichlorophenyl 4,5,6,7-tetrafluoro-2-methylbenzo[b]furan-3-sulphonate (C15H6Cl2F4O4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 2,4-dichlorophenyl 4,5,6,7-tetrafluoro-2-methylbenzo[b]furan-3-sulphonate 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.
