Chemical Structure
Description
CATO supplies Trifluoro-methanesulfonic acid (1,1-dimethylbutyl)dimethylsilyl ester (CAS 2733915-93-8), a certified reference material (molecular formula C9H19F3O3SSi, MW 292.39 g/mol) for analytical method development and quality control.
The molecular framework of Trifluoro-methanesulfonic acid (1,1-dimethylbutyl)dimethylsilyl ester (C9H19F3O3SSi) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
