Chemical Structure
Description
The occurrence of EThyl perfluoro-9-methyl-8-oxadecanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
EThyl perfluoro-9-methyl-8-oxadecanoate (CAS 1211025-06-7), molecular formula C12H5F19O3 and molecular weight 558.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of EThyl perfluoro-9-methyl-8-oxadecanoate (C12H5F19O3) 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.
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.
