Chemical Structure
Description
The molecular framework of Diethylisopropylsilyl Trifluoromethanesulfonate (C8H17F3O3SSi) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
Diethylisopropylsilyl Trifluoromethanesulfonate (CAS 126889-55-2) is a high-purity analytical reference standard with the molecular formula C8H17F3O3SSi and a molecular weight of 278.36 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Diethylisopropylsilyl Trifluoromethanesulfonate 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.
