Chemical Structure
Description
The molecular framework of 5-Bromo-2,3-difluoro-4-(trimethylsilyl)benzoic acid (C10H11BrF2O2Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
5-Bromo-2,3-difluoro-4-(trimethylsilyl)benzoic acid (CAS 1241948-58-2) is a high-purity analytical reference standard with the molecular formula C10H11BrF2O2Si and a molecular weight of 309.18 g/mol.
