Chemical Structure
Description
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.
2-Fluoro-3-(trifluoromethyl)benzyl Bromide (CAS 184970-25-0) is a high-purity analytical reference standard with the molecular formula C8H5BrF4 and a molecular weight of 257.02 g/mol.
Owing to fluorine/bromine substitution, an aromatic ring system, 2-Fluoro-3-(trifluoromethyl)benzyl Bromide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.02 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).
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.
