Chemical Structure
Description
The molecular framework of 157373-00-7 3 - Chloro - 2,4 - difluorobenzoyl chloride 3-Chloro-2,4-difluoro-benzoyl chloride 3-chloro-2,4-difluorobenzoyl chloride 3-chloro-2,4-difluorobenzyl chloride benzoyl chloride, 3-chloro-2,4-difluoro- (9ci) (C7H2Cl2F2O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine 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).
