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-(1-(4-Bromophenyl)ethyl)-1,3-dioxolane (CAS 74100-62-2), molecular formula C11H13BrO2 and molecular weight 257.12 g/mol, is a CATO reference standard with documented purity and traceability.
2-(1-(4-Bromophenyl)ethyl)-1,3-dioxolane (C11H13BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-(1-(4-Bromophenyl)ethyl)-1,3-dioxolane 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.
