Chemical Structure
Description
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.
1,1,2,2-Tetrafluoro-1-(1,1,2,2-tetrafluoro-2-(trifluoromethoxy)ethoxy)-2-(trifluoromethoxy)ethane (CAS 40891-99-4) is a high-purity analytical reference standard with the molecular formula C6F14O3 and a molecular weight of 386.04 g/mol.
Structurally, 1,1,2,2-Tetrafluoro-1-(1,1,2,2-tetrafluoro-2-(trifluoromethoxy)ethoxy)-2-(trifluoromethoxy)ethane (C6F14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 386.04 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
