Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Trifluoro-methanesulfonic acid tris(2-methylpropyl)silyl ester.
CATO supplies Trifluoro-methanesulfonic acid tris(2-methylpropyl)silyl ester (CAS 2408942-54-9), a certified reference material (molecular formula C13H27F3O3SSi, MW 348.50 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Trifluoro-methanesulfonic acid tris(2-methylpropyl)silyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
