Description
As a certified reference material (CRM), 2,2'-(Adipoylbis(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.
2,2'-(Adipoylbis(oxy))bis(3,5-dibromobenzoic acid) (CAS 75848-76-9) is a high-purity analytical reference standard with the molecular formula C20H14Br4O8 and a molecular weight of 701.94 g/mol.
The molecular framework of 2,2'-(Adipoylbis(oxy))bis(3,5-dibromobenzoic acid) (C20H14Br4O8) 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 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.
