Description
CATO supplies 25373-20-0 3,4-Dibromothiophene-2,5-dicarboxaldehyde DTXSID80460643 (CAS 25373-20-0), a certified reference material (molecular formula C6H6Br2O2S, MW 301.98 g/mol) for analytical method development and quality control.
25373-20-0 3,4-Dibromothiophene-2,5-dicarboxaldehyde DTXSID80460643 (C6H6Br2O2S) contains a sulfone group, 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. 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.
As a certified reference material (CRM), 25373-20-0 3,4-Dibromothiophene-2,5-dicarboxaldehyde DTXSID80460643 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.
