Chemical Structure
Description
CATO manufactures (2''-Methyl-[1,1':4',1''-terphenyl]-4-yl)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.
(2''-Methyl-[1,1':4',1''-terphenyl]-4-yl)boronic acid (CAS 491595-39-2) is a high-purity analytical reference standard with the molecular formula C19H17BO2 and a molecular weight of 288.15 g/mol.
The molecular framework of (2''-Methyl-[1,1':4',1''-terphenyl]-4-yl)boronic acid (C19H17BO2) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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.
