Chemical Structure

4-Benzyloxy-3-chloro-5-fluorobenzeneboronic acid pinacol ester CAS 2121515-13-5 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-Benzyloxy-3-chloro-5-fluorobenzeneboronic acid pinacol ester.

CATO supplies 4-Benzyloxy-3-chloro-5-fluorobenzeneboronic acid pinacol ester (CAS 2121515-13-5), a certified reference material (molecular formula C19H23BClFO4, MW 380.65 g/mol) for analytical method development and quality control.

The molecular framework of 4-Benzyloxy-3-chloro-5-fluorobenzeneboronic acid pinacol ester (C19H23BClFO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.

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.

CATO manufactures 4-Benzyloxy-3-chloro-5-fluorobenzeneboronic 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.
