Chemical Structure
Description
4-(tert-Butoxy)-2,3,5,6-tetrafluorostyrene (CAS 343305-41-9), molecular formula C12H12F4O and molecular weight 248.22 g/mol, is a CATO reference standard with documented purity and traceability.
4-(tert-Butoxy)-2,3,5,6-tetrafluorostyrene (C12H12F4O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
