Chemical Structure
Description
(2-Ethyl-5-fluoropyridin-4-yl)boronic acid (C7H9BFNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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).
(2-Ethyl-5-fluoropyridin-4-yl)boronic acid (CAS 2225176-50-9), molecular formula C7H9BFNO2 and molecular weight 168.96 g/mol, is a CATO reference standard with documented purity and traceability.
