Chemical Structure

Trifluoro-methanesulfonic acid (chloromethyl)methyl(2-methyl-4-penten-1-yl)silyl ester CAS 1132657-36-3 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 (chloromethyl)methyl(2-methyl-4-penten-1-yl)silyl ester (CAS 1132657-36-3), molecular formula C9H16ClF3O3SSi and molecular weight 324.82 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Trifluoro-methanesulfonic acid (chloromethyl)methyl(2-methyl-4-penten-1-yl)silyl ester (C9H16ClF3O3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 324.82 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.
