Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4,5-Dimethyl-2-(trimethylsilyl)phenyl trifluoromethanesulfonate (CAS 458566-99-9), a certified reference material (molecular formula C12H17F3O3SSi, MW 326.41 g/mol) for analytical method development and quality control.
The molecular framework of 4,5-Dimethyl-2-(trimethylsilyl)phenyl trifluoromethanesulfonate (C12H17F3O3SSi) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4,5-Dimethyl-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.
