Chemical Structure
Description
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.
Trifluoro-methanesulfonic acid (1,1-dimethylbutyl)bis(1-methylethyl)silyl ester (CAS 1026271-34-0), molecular formula C13H27F3O3SSi and molecular weight 348.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Trifluoro-methanesulfonic acid (1,1-dimethylbutyl)bis(1-methylethyl)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. 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.
