Chemical Structure
Description
CATO supplies 3-Ethoxy-4-fluoro-5-(trifluoromethyl)phenylboronic acid (CAS 2096341-62-5), a certified reference material (molecular formula C9H9BF4O3, MW 251.97 g/mol) for analytical method development and quality control.
The molecular framework of 3-Ethoxy-4-fluoro-5-(trifluoromethyl)phenylboronic acid (C9H9BF4O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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. 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.
As a certified reference material (CRM), 3-Ethoxy-4-fluoro-5-(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.
