Chemical Structure
Description
CATO supplies 4,4,5,5-Tetramethyl-2-(4-((methylthio)methyl)phenyl)-1,3,2-dioxaborolane (CAS 879487-00-0), a certified reference material (molecular formula C14H21BO2S, MW 264.19 g/mol) for analytical method development and quality control.
The molecular framework of 4,4,5,5-Tetramethyl-2-(4-((methylthio)methyl)phenyl)-1,3,2-dioxaborolane (C14H21BO2S) is characterized by a sulfone group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 4,4,5,5-Tetramethyl-2-(4-((methylthio)methyl)phenyl)-1,3,2-dioxaborolane 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.
