Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Chloro-2-fluoro-5-(trifluoromethyl)phenyl)boronic acid.
(3-Chloro-2-fluoro-5-(trifluoromethyl)phenyl)boronic acid (CAS 2096342-38-8), molecular formula C7H4BClF4O2 and molecular weight 242.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-Chloro-2-fluoro-5-(trifluoromethyl)phenyl)boronic acid (C7H4BClF4O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (3-Chloro-2-fluoro-5-(trifluoromethyl)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.
