Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
ethyl 1-(iodomethyl)-3-[4-(trifluoromethyl)phenyl]-2-oxabicyclo[2.2.2]octane-4-carboxylate (CAS 2703774-37-0), molecular formula C18H20F3IO3 and molecular weight 468.25 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H20F3IO3, ethyl 1-(iodomethyl)-3-[4-(trifluoromethyl)phenyl]-2-oxabicyclo[2.2.2]octane-4-carboxylate contains a steroid core, a hydroxyl group, an ether linkage, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 468.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
