2-Bromo-4,5-difluorobenzoyl chloride (CAS 103994-89-4), molecular formula C7H2BrClF2O and molecular weight 255.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-4,5-difluorobenzoyl chloride (C7H2BrClF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine/bromine 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
