Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 195.05 g/mol gives 2-bromobutyl acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-bromobutyl acetate (CAS 13333-04-5), molecular formula C6H11BrO2 and molecular weight 195.05 g/mol, is a CATO reference standard with documented purity and traceability.
2-bromobutyl acetate (C6H11BrO2) 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.
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), 2-bromobutyl acetate 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.
