Chemical Structure
Description
The occurrence of 4,5-Difluoro-2-(trimethylsilyl)phenyl trifluoromethanesulfonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,5-Difluoro-2-(trimethylsilyl)phenyl trifluoromethanesulfonate (CAS 217813-00-8), molecular formula C10H11F5O3SSi and molecular weight 334.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,5-Difluoro-2-(trimethylsilyl)phenyl trifluoromethanesulfonate (C10H11F5O3SSi) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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 4,5-Difluoro-2-(trimethylsilyl)phenyl 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.
