Description
As a certified reference material (CRM), 5-(3-Bromophenyl)benzo[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-(3-Bromophenyl)benzo[d][1,3]dioxole (CAS 1443327-79-4), a certified reference material (molecular formula C13H9BrO2, MW 277.11 g/mol) for analytical method development and quality control.
5-(3-Bromophenyl)benzo[d][1,3]dioxole (C13H9BrO2) 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. 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.
