Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 233.02 g/mol gives 3-Bromo-2,6-dihydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-2,6-dihydroxybenzoic acid (CAS 26792-49-4), molecular formula C7H5BrO4 and molecular weight 233.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-2,6-dihydroxybenzoic acid (C7H5BrO4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Bromo-2,6-dihydroxybenzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
