Chemical Structure
Description
The molecular framework of 2,3-Difluoro-1-iodo-4-methoxybenzene (C7H5F2IO) is characterized by a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
