Chemical Structure
Description
The occurrence of 4,5-Dimethoxy-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.
CATO supplies 4,5-Dimethoxy-2-(trimethylsilyl)phenyl Trifluoromethanesulfonate (CAS 866252-52-0), a certified reference material (molecular formula C12H17F3O5SSi, MW 358.41 g/mol) for analytical method development and quality control.
The molecular framework of 4,5-Dimethoxy-2-(trimethylsilyl)phenyl Trifluoromethanesulfonate (C12H17F3O5SSi) 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. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
