Chemical Structure
Description
The molecular framework of Trifluoro-methanesulfonic acid (1,1-dimethylethyl)bis(2-methylpropyl)silyl ester (C13H27F3O3SSi) 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.
Trifluoro-methanesulfonic acid (1,1-dimethylethyl)bis(2-methylpropyl)silyl ester (CAS 561322-39-2) is a high-purity analytical reference standard with the molecular formula C13H27F3O3SSi and a molecular weight of 348.50 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.
