Description
The occurrence of methyl 1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-{2-[2,6-dichloro-4-(trifluoromethyl)phenyl]hydrazono}-5-oxo-4,5-dihydro-1H-pyrazole-3-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
methyl 1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-{2-[2,6-dichloro-4-(trifluoromethyl)phenyl]hydrazono}-5-oxo-4,5-dihydro-1H-pyrazole-3-carboxylate (CAS 259175-31-0) is a high-purity analytical reference standard with the molecular formula C19H8Cl4F6N4O3 and a molecular weight of 596.09 g/mol.
methyl 1-[2,6-dichloro-4-(trifluoromethyl)phenyl]-4-{2-[2,6-dichloro-4-(trifluoromethyl)phenyl]hydrazono}-5-oxo-4,5-dihydro-1H-pyrazole-3-carboxylate (C19H8Cl4F6N4O3) contains a steroid core, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
