Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 4-Fluoro-3-trifluoromethylbenzeneboronic acid, 97% is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.92 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).
4-Fluoro-3-trifluoromethylbenzeneboronic acid, 97% (CAS 182344-23-6) is a high-purity analytical reference standard with the molecular formula C7H5BF4O2 and a molecular weight of 207.92 g/mol.
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.
