2,3,5,6-Tetrafluorophenylhydrazine (CAS 653-11-2) is a high-purity analytical reference standard with the molecular formula C6H4F4N2 and a molecular weight of 180.10 g/mol.
2,3,5,6-Tetrafluorophenylhydrazine (C6H4F4N2) contains a nitrile group, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
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.
