Chemical Structure
Description
The molecular framework of 4,4,5,5-Tetramethyl-2-(3-(methylthio)phenyl)-1,3,2-dioxaborolane (C13H19BO2S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
4,4,5,5-Tetramethyl-2-(3-(methylthio)phenyl)-1,3,2-dioxaborolane (CAS 710348-63-3) is a high-purity analytical reference standard with the molecular formula C13H19BO2S and a molecular weight of 250.16 g/mol.
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.
