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.
1,1,1,2,4,4,5,7,7,8,10,10,11,13,13,14,14,15,15,15-Icosafluoro-5,8,11-tris(trifluoromethyl)-3,6,9,12-tetraoxapentadecane (CAS 26738-51-2), molecular formula C14HF29O4 and molecular weight 784.11 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, 1,1,1,2,4,4,5,7,7,8,10,10,11,13,13,14,14,15,15,15-Icosafluoro-5,8,11-tris(trifluoromethyl)-3,6,9,12-tetraoxapentadecane is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 784.11 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.
