Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 291.07 g/mol gives Dimethyl 2-bromo-5-Fluoroterephthalic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dimethyl 2-bromo-5-Fluoroterephthalic acid (CAS 1245807-10-6), molecular formula C10H8BrFO4 and molecular weight 291.07 g/mol, is a CATO reference standard with documented purity and traceability.
Dimethyl 2-bromo-5-Fluoroterephthalic acid (C10H8BrFO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Dimethyl 2-bromo-5-Fluoroterephthalic 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.
