Chemical Structure
Description
4-Chloro-N'-{[5-oxo-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-4-ylidene]methyl}benzohydrazide (CAS 338975-58-9) is a high-purity analytical reference standard with the molecular formula C12H8ClF3N4O2 and a molecular weight of 332.67 g/mol.
4-Chloro-N'-{[5-oxo-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-4-ylidene]methyl}benzohydrazide (C12H8ClF3N4O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
