Chemical Structure
Description
As a certified reference material (CRM), 2-Chloro-3-(trifluoromethyl)phenylboronic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-Chloro-3-(trifluoromethyl)phenylboronic Acid (CAS 957061-11-9) is a high-purity analytical reference standard with the molecular formula C7H5BClF3O2 and a molecular weight of 224.37 g/mol.
The molecular framework of 2-Chloro-3-(trifluoromethyl)phenylboronic Acid (C7H5BClF3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
