Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-(2-Bromo-1,1-dimethyl-ethyl)-2,2-dimethyl-[1,3]dioxolane (CAS 2228141-73-7), molecular formula C9H17BrO2 and molecular weight 237.13 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2-Bromo-1,1-dimethyl-ethyl)-2,2-dimethyl-[1,3]dioxolane (C9H17BrO2) contains a carboxylic acid 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.
As a certified reference material (CRM), 4-(2-Bromo-1,1-dimethyl-ethyl)-2,2-dimethyl-[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.
