Chemical Structure

2,3,5,6-Tetrafluoro-4-nitropyridine CAS 3511-89-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 196.06 g/mol gives 2,3,5,6-Tetrafluoro-4-nitropyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,3,5,6-Tetrafluoro-4-nitropyridine (CAS 3511-89-5) is a high-purity analytical reference standard with the molecular formula C5F4N2O2 and a molecular weight of 196.06 g/mol.

The molecular framework of 2,3,5,6-Tetrafluoro-4-nitropyridine (C5F4N2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
