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 2-Fluoro-4-methoxybenzeneboronic acid pinacol ester, 97%.
CATO supplies 2-Fluoro-4-methoxybenzeneboronic acid pinacol ester, 97% (CAS 628692-21-7), a certified reference material (molecular formula C13H17BClFO3, MW 286.53 g/mol) for analytical method development and quality control.
The molecular framework of 2-Fluoro-4-methoxybenzeneboronic acid pinacol ester, 97% (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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 2-Fluoro-4-methoxybenzeneboronic acid pinacol ester, 97% 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.
