Chemical Structure
Description
(E)-3-(2-(4-bromo-2-fluorophenoxy)phenyl)acrylic acid (C15H10BrFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system. 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. 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).
(E)-3-(2-(4-bromo-2-fluorophenoxy)phenyl)acrylic acid (CAS 449778-69-2), molecular formula C15H10BrFO3 and molecular weight 337.14 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
