Description
CATO manufactures 4-Chlorobenzylboronic 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.
4-Chlorobenzylboronic Acid Pinacol Ester (CAS 475250-49-8), molecular formula C13H18BClO2 and molecular weight 252.54 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chlorobenzylboronic Acid Pinacol Ester (C13H18BClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
