Chemical Structure

(4-((Tert-butyldimethylsilyl)oxy)-3-methoxyphenyl)boronic acid CAS 957060-93-4 chemical structure

Description

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.

(4-((Tert-butyldimethylsilyl)oxy)-3-methoxyphenyl)boronic acid (CAS 957060-93-4) is a high-purity analytical reference standard with the molecular formula C13H23BO4Si and a molecular weight of 282.22 g/mol.

(4-((Tert-butyldimethylsilyl)oxy)-3-methoxyphenyl)boronic acid (C13H23BO4Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
