N'4-(2,3,3-trichloroacryloyl)-1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carbohydrazide CAS 648859-36-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 427.59 g/mol gives N'4-(2,3,3-trichloroacryloyl)-1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carbohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N'4-(2,3,3-trichloroacryloyl)-1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carbohydrazide (CAS 648859-36-3) is a high-purity analytical reference standard with the molecular formula C14H8Cl3F3N4O2 and a molecular weight of 427.59 g/mol.

N'4-(2,3,3-trichloroacryloyl)-1-phenyl-5-(trifluoromethyl)-1H-pyrazole-4-carbohydrazide (C14H8Cl3F3N4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, 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).
