2-(2-Chloro-6-fluorobenzylidene)-5-oxopyrazolidin-2-ium-1-ide (CAS 338779-27-4), molecular formula C10H8ClFN2O and molecular weight 226.63 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-Chloro-6-fluorobenzylidene)-5-oxopyrazolidin-2-ium-1-ide (C10H8ClFN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
