Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 360.90 g/mol gives 3-bromo-2-fluoro-4-hydroxy-5-iodobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-bromo-2-fluoro-4-hydroxy-5-iodobenzoic acid (CAS 2770534-72-8) is a high-purity analytical reference standard with the molecular formula C7H3BrFIO3 and a molecular weight of 360.90 g/mol.
The molecular framework of 3-bromo-2-fluoro-4-hydroxy-5-iodobenzoic acid (C7H3BrFIO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine 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 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.
