Chemical Structure
Description
3-(4-Butoxy-3-fluoro-phenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (C20H19FN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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).
3-(4-Butoxy-3-fluoro-phenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 882231-94-9), molecular formula C20H19FN2O2 and molecular weight 338.38 g/mol, is a CATO reference standard with documented purity and traceability.
