Chemical Structure
Description
The molecular framework of 2,6-Dibromobenzene-1,4-diol (C6H4Br2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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).
2,6-Dibromobenzene-1,4-diol (CAS 3333-25-3) is a high-purity analytical reference standard with the molecular formula C6H4Br2O2 and a molecular weight of 267.90 g/mol.
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), 2,6-Dibromobenzene-1,4-diol 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.
