Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 271.88 g/mol gives 1,5-Dibromo-2,4-difluorobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,5-Dibromo-2,4-difluorobenzene (CAS 28342-75-8), a certified reference material (molecular formula C6H2Br2F2, MW 271.88 g/mol) for analytical method development and quality control.
1,5-Dibromo-2,4-difluorobenzene (C6H2Br2F2) contains fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 1,5-Dibromo-2,4-difluorobenzene 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.
