Description
As a certified reference material (CRM), 3-(Difluoromethyl)-8-((triisopropylsilyl)ethynyl)naphthalen-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.
CATO supplies 3-(Difluoromethyl)-8-((triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate (CAS 2856022-11-0), a certified reference material (molecular formula C23H27F5O3SSi, MW 506.60 g/mol) for analytical method development and quality control.
3-(Difluoromethyl)-8-((triisopropylsilyl)ethynyl)naphthalen-1-yl trifluoromethanesulfonate (C23H27F5O3SSi) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
