Description

Compared with other compounds in its class, the molecular weight of 618.09 g/mol gives 1,1,1,2,2,3,3-Heptafluoro-3-[[1,1,1,2,3,3-hexafluoro-3-[[1,1,1,2,3,3-hexafluoro-3-(1,2,2,2-tetrafluoroethoxy)propan-2-yl]oxy]propan-2-yl]oxy]propane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,1,1,2,2,3,3-Heptafluoro-3-[[1,1,1,2,3,3-hexafluoro-3-[[1,1,1,2,3,3-hexafluoro-3-(1,2,2,2-tetrafluoroethoxy)propan-2-yl]oxy]propan-2-yl]oxy]propane (CAS 3330-16-3), molecular formula C11HF23O3 and molecular weight 618.09 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 1,1,1,2,2,3,3-Heptafluoro-3-[[1,1,1,2,3,3-hexafluoro-3-[[1,1,1,2,3,3-hexafluoro-3-(1,2,2,2-tetrafluoroethoxy)propan-2-yl]oxy]propan-2-yl]oxy]propane is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 618.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
