Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 257.86 g/mol gives 3,4-Dibromodihydrofuran-2,5-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,4-Dibromodihydrofuran-2,5-dione (CAS 45669-18-9), a certified reference material (molecular formula C4H2Br2O3, MW 257.86 g/mol) for analytical method development and quality control.
3,4-Dibromodihydrofuran-2,5-dione (C4H2Br2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
