As a certified reference material (CRM), 4-((Tert-butyldimethylsilyl)oxy)-7-fluoronaphthalen-2-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.
4-((Tert-butyldimethylsilyl)oxy)-7-fluoronaphthalen-2-yl trifluoromethanesulfonate (CAS 2449057-86-5), molecular formula C17H20F4O4SSi and molecular weight 424.48 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 4-((Tert-butyldimethylsilyl)oxy)-7-fluoronaphthalen-2-yl trifluoromethanesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
