Chemical Structure

1,2-Bis(2-fluorophenyl)hydrazine CAS 454-21-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 220.22 g/mol gives 1,2-Bis(2-fluorophenyl)hydrazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2-Bis(2-fluorophenyl)hydrazine (CAS 454-21-7), molecular formula C12H10F2N2 and molecular weight 220.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H10F2N2, 1,2-Bis(2-fluorophenyl)hydrazine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
