2-(Difluoromethyl)-3,6-diiodopyridine-5-carboxaldehyde CAS 1803705-19-2

Description

The molecular framework of 2-(Difluoromethyl)-3,6-diiodopyridine-5-carboxaldehyde (C7H3F2I2NO) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/iodine 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. 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).
