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.
2,2,6,6-Tetramethyl-1-oxopiperidinium tetrafluoroborate (CAS 33247-78-8) is a high-purity analytical reference standard with the molecular formula C9H18NOBF3F and a molecular weight of 243.05 g/mol.
Based on its molecular formula C9H18NOBF3F, 2,2,6,6-Tetramethyl-1-oxopiperidinium tetrafluoroborate contains an amide 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 243.05 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.
