2-(4-Bromo-5-methyl-3-(trifluoromethyl)-1h-pyrazol-1-yl)acetohydrazide (CAS 1004644-67-0), molecular formula C7H8BrF3N4O and molecular weight 301.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(4-Bromo-5-methyl-3-(trifluoromethyl)-1h-pyrazol-1-yl)acetohydrazide (C7H8BrF3N4O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
