CATO manufactures (3-Chloro-4-ethoxy-5-fluorophenyl)boronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(3-Chloro-4-ethoxy-5-fluorophenyl)boronic acid (CAS 2096334-30-2) is a high-purity analytical reference standard with the molecular formula C8H9BClFO3 and a molecular weight of 218.42 g/mol.
The molecular framework of (3-Chloro-4-ethoxy-5-fluorophenyl)boronic acid (C8H9BClFO3) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
