Description
As a certified reference material (CRM), 5-Bromo-6-chlorobenzo[d][1,3]dioxole 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.
CATO supplies 5-Bromo-6-chlorobenzo[d][1,3]dioxole (CAS 233770-05-3), a certified reference material (molecular formula C7H4BrClO2, MW 235.46 g/mol) for analytical method development and quality control.
5-Bromo-6-chlorobenzo[d][1,3]dioxole (C7H4BrClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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. 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.
