Description
4',7'-Dibromodispiro[1,3-dioxolane-2,3'-tricyclo[5.2.1.0,2,6]decane-10',2''-[1,3]dioxolane]-4',8'-diene (CAS 485318-53-4), molecular formula C14H14Br2O4 and molecular weight 406.07 g/mol, is a CATO reference standard with documented purity and traceability.
4',7'-Dibromodispiro[1,3-dioxolane-2,3'-tricyclo[5.2.1.0,2,6]decane-10',2''-[1,3]dioxolane]-4',8'-diene (C14H14Br2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4',7'-Dibromodispiro[1,3-dioxolane-2,3'-tricyclo[5.2.1.0,2,6]decane-10',2''-[1,3]dioxolane]-4',8'-diene 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.
