Chemical Structure
Description
The molecular framework of 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-3-(trifluoromethyl)quinoxaline (C14H11F3N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-3-(trifluoromethyl)quinoxaline (CAS 321538-05-0), a certified reference material (molecular formula C14H11F3N4, MW 292.26 g/mol) for analytical method development and quality control.
