Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 296.34 g/mol gives Trifluoro-methanesulfonic acid ethenylmethylphenylsilyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trifluoro-methanesulfonic acid ethenylmethylphenylsilyl ester (CAS 150443-38-2), molecular formula C10H11F3O3SSi and molecular weight 296.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Trifluoro-methanesulfonic acid ethenylmethylphenylsilyl ester (C10H11F3O3SSi) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
CATO manufactures Trifluoro-methanesulfonic acid ethenylmethylphenylsilyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
