Chemical Structure

3,4-Bis(trifluoromethyl)phenylboronic Acid CAS 1204745-88-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 257.93 g/mol gives 3,4-Bis(trifluoromethyl)phenylboronic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,4-Bis(trifluoromethyl)phenylboronic Acid (CAS 1204745-88-9) is a high-purity analytical reference standard with the molecular formula C8H5BF6O2 and a molecular weight of 257.93 g/mol.

3,4-Bis(trifluoromethyl)phenylboronic Acid (C8H5BF6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
