1,2-Bis(4-nitrophenyl)ethane-1,2-dione CAS 6067-45-4

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.

1,2-Bis(4-nitrophenyl)ethane-1,2-dione (CAS 6067-45-4) is a high-purity analytical reference standard with the molecular formula C14H8N2O6 and a molecular weight of 300.22 g/mol.

Based on its molecular formula C14H8N2O6, 1,2-Bis(4-nitrophenyl)ethane-1,2-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
