Chemical Structure
Description
The occurrence of 1,1,1,2,2-Pentafluoro-3-methylbutan-3-ol 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.
1,1,1,2,2-Pentafluoro-3-methylbutan-3-ol (CAS 374-46-9), molecular formula C5H7F5O and molecular weight 178.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H7F5O, 1,1,1,2,2-Pentafluoro-3-methylbutan-3-ol contains a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 178.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
