5-Chloro-1-(4-chlorophenyl)-3-ethyl-1H-pyrazole-4-carbaldehyde (CAS 1152575-68-2), molecular formula C12H10Cl2N2O and molecular weight 269.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Chloro-1-(4-chlorophenyl)-3-ethyl-1H-pyrazole-4-carbaldehyde (C12H10Cl2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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).
