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 4-Chloro-3-fluoro-2-methoxyphenylboronic acid pinacol ester.
4-Chloro-3-fluoro-2-methoxyphenylboronic acid pinacol ester (CAS 1628524-83-3), molecular formula C13H17BClFO3 and molecular weight 286.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-3-fluoro-2-methoxyphenylboronic acid pinacol ester (C13H17BClFO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-Chloro-3-fluoro-2-methoxyphenylboronic acid pinacol ester 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.
