Chemical Structure
Description
23868-34-0 TBABF Tetrabutylammonium bifluoride Tetrabutylammonium difluoride Tetrabutylammonium hydrogen difluoride solution (C16H36NHFF) contains fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 23868-34-0 TBABF Tetrabutylammonium bifluoride Tetrabutylammonium difluoride Tetrabutylammonium hydrogen difluoride solution (CAS 23868-34-0), a certified reference material (molecular formula C16H36NHFF, MW 281.47 g/mol) for analytical method development and quality control.
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.
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.
