Chemical Structure
Description
The molecular framework of (E)-2,2'-(Fumaroylbis(oxy))bis(3,5-dibromobenzoic acid) (C18H8Br4O8) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
(E)-2,2'-(Fumaroylbis(oxy))bis(3,5-dibromobenzoic acid) (CAS CATO-C3D-263101), molecular formula C18H8Br4O8 and molecular weight 671.87 g/mol, is a CATO reference standard with documented purity and traceability.
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), (E)-2,2'-(Fumaroylbis(oxy))bis(3,5-dibromobenzoic acid) 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.
