Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 2-Bromo-4-fluoro-1-((2,2,2-trifluoroethoxy)methyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
2-Bromo-4-fluoro-1-((2,2,2-trifluoroethoxy)methyl)benzene (CAS 1248443-45-9), molecular formula C9H7BrF4O and molecular weight 287.05 g/mol, is a CATO reference standard with documented purity and traceability.
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.
