2,5-Bis(4-Fluorophenyl)-3,6-Diphenyl-1,4-Benzoquinone CAS 22030-92-8

Description

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.

2,5-Bis(4-Fluorophenyl)-3,6-Diphenyl-1,4-Benzoquinone (CAS 22030-92-8) is a high-purity analytical reference standard with the molecular formula C30H18F2O2 and a molecular weight of 448.46 g/mol.

Based on its molecular formula C30H18F2O2, 2,5-Bis(4-Fluorophenyl)-3,6-Diphenyl-1,4-Benzoquinone contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 448.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
