Chemical Structure
Description
As a certified reference material (CRM), (3-Chloro-4-(trifluoromethoxy)phenyl)boronic 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.
(3-Chloro-4-(trifluoromethoxy)phenyl)boronic acid (CAS 870822-79-0), molecular formula C7H5BClF3O3 and molecular weight 240.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-Chloro-4-(trifluoromethoxy)phenyl)boronic acid (C7H5BClF3O3) 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.
