Chemical Structure

4,4,5,5-Tetramethyl-2-(m-pentafluorosulfanylbenzene)-1,3,2-dioxaborolane CAS 1286278-35-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 330.12 g/mol gives 4,4,5,5-Tetramethyl-2-(m-pentafluorosulfanylbenzene)-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4,5,5-Tetramethyl-2-(m-pentafluorosulfanylbenzene)-1,3,2-dioxaborolane (CAS 1286278-35-0) is a high-purity analytical reference standard with the molecular formula C12H16BF5O2S and a molecular weight of 330.12 g/mol.

The molecular framework of 4,4,5,5-Tetramethyl-2-(m-pentafluorosulfanylbenzene)-1,3,2-dioxaborolane (C12H16BF5O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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.
