Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 231.04 g/mol gives 3-Bromo-2-hydroxy-6-methylbenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-2-hydroxy-6-methylbenzoic acid (CAS 681467-89-0), molecular formula C8H7BrO3 and molecular weight 231.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-2-hydroxy-6-methylbenzoic acid (C8H7BrO3) 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 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.
