Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
4,4,5,5-Tetramethyl-2-(2,4,6-trimethylphenyl)-1,3,2-dioxaborolane (CAS 171364-84-4) is a high-purity analytical reference standard with the molecular formula C15H23BO2 and a molecular weight of 246.15 g/mol.
The molecular framework of 4,4,5,5-Tetramethyl-2-(2,4,6-trimethylphenyl)-1,3,2-dioxaborolane (C15H23BO2) 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).
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.
