Chemical Structure
Description
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.
1,1,1-Trifluoro-5-methoxy-5-methylhexane-2,4-dione (CAS 146195-65-5), molecular formula C8H11F3O3 and molecular weight 212.17 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H11F3O3, 1,1,1-Trifluoro-5-methoxy-5-methylhexane-2,4-dione contains a carboxylic acid group, 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 212.17 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
