1-(4-Bromophenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carbohydrazide (CAS 618090-98-5) is a high-purity analytical reference standard with the molecular formula C11H8BrF3N4O and a molecular weight of 349.11 g/mol.

The molecular framework of 1-(4-Bromophenyl)-5-(trifluoromethyl)-1H-pyrazole-4-carbohydrazide (C11H8BrF3N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
