Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (R)-Triethyl((1-fluoro-2-methylbut-3-yn-2-yl)oxy)silane (CAS 2659374-77-1), a certified reference material (molecular formula C11H21FOSi, MW 216.37 g/mol) for analytical method development and quality control.
(R)-Triethyl((1-fluoro-2-methylbut-3-yn-2-yl)oxy)silane (C11H21FOSi) contains 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; 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.
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.
