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.
Perfluoro-2,5-dimethyl-3,6-dioxanonanoic acid methyl ester (CAS 26131-32-8), molecular formula C10H3F17O4 and molecular weight 510.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Perfluoro-2,5-dimethyl-3,6-dioxanonanoic acid methyl ester (C10H3F17O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
