Chemical Structure
Description
The molecular framework of 4-Bromo-1-isopentyl-3-(trifluoromethyl)-1H-pyrazole (C9H12BrF3N2) is characterized by a nitrile group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
