Chemical Structure
Description
Propyl 4-((3-(2,4-dihydroxyphenyl)-1H-pyrazol-4-yl)oxy)benzoate (C19H18N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
Propyl 4-((3-(2,4-dihydroxyphenyl)-1H-pyrazol-4-yl)oxy)benzoate (CAS 879458-58-9), molecular formula C19H18N2O5 and molecular weight 354.36 g/mol, is a CATO reference standard with documented purity and traceability.
