Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1,1-trifluoro-2-undecanol 1,1,1-tris(fluoranyl)undecan-2-ol 181933-95-9 A812644 (CAS 181933-95-9), molecular formula C11H21F3O and molecular weight 226.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, 1,1,1-trifluoro-2-undecanol 1,1,1-tris(fluoranyl)undecan-2-ol 181933-95-9 A812644 is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 226.28 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.
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.
