Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 251.09 g/mol gives 7-bromo-4-fluoro-benzofuran-5-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-bromo-4-fluoro-benzofuran-5-carbaldehyde (CAS 2640071-70-9), molecular formula C9H12BrFO2 and molecular weight 251.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-bromo-4-fluoro-benzofuran-5-carbaldehyde (C9H12BrFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. 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).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
