Compared with other compounds in its class, the molecular weight of 166.51 g/mol gives 2,4-Difluoro-1H-imidazole-5-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,4-Difluoro-1H-imidazole-5-carbonyl chloride (CAS 89676-64-2), a certified reference material (molecular formula C4HClF2N2O, MW 166.51 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-Difluoro-1H-imidazole-5-carbonyl chloride (C4HClF2N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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).
