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.
EThyl perfluoro-2,5,8,10-tetramethyl-3,6,9-trioxaundecanoate (CAS 1212156-86-9), molecular formula C14H5F23O5 and molecular weight 690.15 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, EThyl perfluoro-2,5,8,10-tetramethyl-3,6,9-trioxaundecanoate is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 690.15 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.
