Chemical Structure
Description
The occurrence of [2,3,3,4,4,4-Hexafluoro-2-(trifluoromethyl)butyl]oxirane is closely related to a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[2,3,3,4,4,4-Hexafluoro-2-(trifluoromethyl)butyl]oxirane (CAS 239463-94-6), molecular formula C7H5F9O and molecular weight 276.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, [2,3,3,4,4,4-Hexafluoro-2-(trifluoromethyl)butyl]oxirane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.10 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.
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.
