Chemical Structure

3-(Chlorosulfonyl)-4-fluorophenylboronic Acid Pinacol Ester CAS 1003575-37-8 chemical structure

Description

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.

3-(Chlorosulfonyl)-4-fluorophenylboronic Acid Pinacol Ester (CAS 1003575-37-8) is a high-purity analytical reference standard with the molecular formula C12H15BClFO4S and a molecular weight of 320.57 g/mol.

The molecular framework of 3-(Chlorosulfonyl)-4-fluorophenylboronic Acid Pinacol Ester (C12H15BClFO4S) is characterized by a sulfone group, 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.

CATO manufactures 3-(Chlorosulfonyl)-4-fluorophenylboronic 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.
