Chemical Structure
Description
As a certified reference material (CRM), Trifluoro-methanesulfonic acid dimethyl(1-methyl-1-phenylethyl)silyl ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Trifluoro-methanesulfonic acid dimethyl(1-methyl-1-phenylethyl)silyl ester (CAS 1027938-82-4) is a high-purity analytical reference standard with the molecular formula C12H17F3O3SSi and a molecular weight of 326.41 g/mol.
Structurally, Trifluoro-methanesulfonic acid dimethyl(1-methyl-1-phenylethyl)silyl ester (C12H17F3O3SSi) 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 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 326.41 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
