Description
As a certified reference material (CRM), 5,6,7,8-Tetrahydronaphthalen-1-yl 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.
5,6,7,8-Tetrahydronaphthalen-1-yl trifluoromethanesulfonate (CAS 101533-70-4), molecular formula C11H11F3O3S and molecular weight 280.26 g/mol, is a CATO reference standard with documented purity and traceability.
5,6,7,8-Tetrahydronaphthalen-1-yl trifluoromethanesulfonate (C11H11F3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
