Description
CATO supplies 1,1,1,3,3,5,5,7,7,9,9,11,11-Tridecafluoro-2,4,6,8,10-pentaoxadodecan-12-oic acid (CAS 39492-91-6), a certified reference material (molecular formula C7HF13O7, MW 444.06 g/mol) for analytical method development and quality control.
1,1,1,3,3,5,5,7,7,9,9,11,11-Tridecafluoro-2,4,6,8,10-pentaoxadodecan-12-oic acid (C7HF13O7) contains a carbohydrate-derived structure, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
