Chemical Structure
Description
4-Bromo-2-fluoro-1-(fluoromethyl)benzene (CAS 2244086-30-2) is a high-purity analytical reference standard with the molecular formula C7H5BrF2 and a molecular weight of 207.02 g/mol.
Owing to fluorine/bromine substitution, an aromatic ring system, 4-Bromo-2-fluoro-1-(fluoromethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
