Description

Compared with other compounds in its class, the molecular weight of 306.42 g/mol gives Trifluoro-methanesulfonic acid dibutylmethylsilyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Trifluoro-methanesulfonic acid dibutylmethylsilyl ester (CAS 1926995-04-1), molecular formula C10H21F3O3SSi and molecular weight 306.42 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Trifluoro-methanesulfonic acid dibutylmethylsilyl ester (C10H21F3O3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 306.42 g/mol, it falls into the moderately-high-molecular-weight range. 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.
