Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(5-methoxy-2-trimethylsilyl-phenyl) trifluoromethanesulfonate (CAS 1301268-25-6), molecular formula C11H21F3O4SSi and molecular weight 334.43 g/mol, is a CATO reference standard with documented purity and traceability.
(5-methoxy-2-trimethylsilyl-phenyl) trifluoromethanesulfonate (C11H21F3O4SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (5-methoxy-2-trimethylsilyl-phenyl) trifluoromethanesulfonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
