Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 263.06 g/mol gives Ethyl 4-bromo-2-fluoro-3-hydroxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4-bromo-2-fluoro-3-hydroxybenzoate (CAS 1807191-25-8), molecular formula C9H8BrFO3 and molecular weight 263.06 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 4-bromo-2-fluoro-3-hydroxybenzoate (C9H8BrFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Ethyl 4-bromo-2-fluoro-3-hydroxybenzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
