Chemical Structure
Description
The molecular framework of Perfluoro-3,6,9-trioxaundecane-1,11-dioic acid (C8H2F12O7) is characterized by a carbohydrate-derived structure, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
Perfluoro-3,6,9-trioxaundecane-1,11-dioic acid (CAS 55621-18-6) is a high-purity analytical reference standard with the molecular formula C8H2F12O7 and a molecular weight of 438.08 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.
