Chemical Structure

2-(4-((tert-Butyldimethylsilyl)oxy)-2-methylbutan-2-yl)-3,5-dimethylphenol CAS 134098-64-9 chemical structure

Description

2-(4-((tert-Butyldimethylsilyl)oxy)-2-methylbutan-2-yl)-3,5-dimethylphenol (C19H34O2Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

2-(4-((tert-Butyldimethylsilyl)oxy)-2-methylbutan-2-yl)-3,5-dimethylphenol (CAS 134098-64-9) is a high-purity analytical reference standard with the molecular formula C19H34O2Si and a molecular weight of 322.56 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
