Chemical Structure
Description
(4-(Ethoxycarbonyl)-2,6-dimethylphenyl)boronic acid (CAS 851335-20-1), molecular formula C11H15BO4 and molecular weight 222.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-(Ethoxycarbonyl)-2,6-dimethylphenyl)boronic acid (C11H15BO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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).
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-(Ethoxycarbonyl)-2,6-dimethylphenyl)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.
