2,3,5,6-Tetrafluoro-N1,N4-dimethyl-N1,N4-diphenylbenzene-1,4-diamine CAS 39068-64-9

Description

The occurrence of 2,3,5,6-Tetrafluoro-N1,N4-dimethyl-N1,N4-diphenylbenzene-1,4-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,3,5,6-Tetrafluoro-N1,N4-dimethyl-N1,N4-diphenylbenzene-1,4-diamine (CAS 39068-64-9), molecular formula C20H16F4N2 and molecular weight 360.35 g/mol, is a CATO reference standard with documented purity and traceability.

2,3,5,6-Tetrafluoro-N1,N4-dimethyl-N1,N4-diphenylbenzene-1,4-diamine (C20H16F4N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
