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.
4-(Hydroxymethyl)-3-methylphenylboronic Acid Pinacol Ester (CAS 1160430-87-4), molecular formula C14H21BO3 and molecular weight 248.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(Hydroxymethyl)-3-methylphenylboronic Acid Pinacol Ester (C14H21BO3) 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).
CATO manufactures 4-(Hydroxymethyl)-3-methylphenylboronic 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.
