Chemical Structure
Description
The molecular framework of 5-Bromo-7-chlorobenzofuran-2-carboxylic acid (C9H4BrClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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.
5-Bromo-7-chlorobenzofuran-2-carboxylic acid (CAS 944692-41-5), molecular formula C9H4BrClO3 and molecular weight 275.48 g/mol, is a CATO reference standard with documented purity and traceability.
