Description
The occurrence of 169289-58-1 2,2-difluoro-2-[1,1,2,2-tetrafluoro-2-[1,1,2,2-tetrafluoro-2-(trifluoromethoxy)ethoxy]ethoxy]acetic acid methyl ester A811085 methyl 2,2-bis(fluoranyl)-2-[1,1,2,2-tetrakis(fluoranyl)-2-[1,1,2,2-tetrakis(fluoranyl)-2-(trifluoromethyloxy)ethoxy]ethoxy]ethanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 169289-58-1 2,2-difluoro-2-[1,1,2,2-tetrafluoro-2-[1,1,2,2-tetrafluoro-2-(trifluoromethoxy)ethoxy]ethoxy]acetic acid methyl ester A811085 methyl 2,2-bis(fluoranyl)-2-[1,1,2,2-tetrakis(fluoranyl)-2-[1,1,2,2-tetrakis(fluoranyl)-2-(trifluoromethyloxy)ethoxy]ethoxy]ethanoate (CAS 169289-58-1), a certified reference material (molecular formula C8H3F13O5, MW 426.09 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H3F13O5, 169289-58-1 2,2-difluoro-2-[1,1,2,2-tetrafluoro-2-[1,1,2,2-tetrafluoro-2-(trifluoromethoxy)ethoxy]ethoxy]acetic acid methyl ester A811085 methyl 2,2-bis(fluoranyl)-2-[1,1,2,2-tetrakis(fluoranyl)-2-[1,1,2,2-tetrakis(fluoranyl)-2-(trifluoromethyloxy)ethoxy]ethoxy]ethanoate 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 426.09 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.
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.
