Chemical Structure
Description
9-Chloroperfluorononanoic acid (C9HClF16O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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.
9-Chloroperfluorononanoic acid (CAS 865-79-2) is a high-purity analytical reference standard with the molecular formula C9HClF16O2 and a molecular weight of 480.53 g/mol.
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.
