Trifluoro-methanesulfonic acid dimethyloctylsilyl ester CAS 136445-80-2

Description

Trifluoro-methanesulfonic acid dimethyloctylsilyl ester (CAS 136445-80-2), molecular formula C11H23F3O3SSi and molecular weight 320.44 g/mol, is a CATO reference standard with documented purity and traceability.

Trifluoro-methanesulfonic acid dimethyloctylsilyl ester (C11H23F3O3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

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.
