Compared with other compounds in its class, the molecular weight of 534.64 g/mol gives 9,10-Anthracenedione, 1,4-bis[(4-butylphenyl)amino]-5,8-dihydroxy- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9,10-Anthracenedione, 1,4-bis[(4-butylphenyl)amino]-5,8-dihydroxy- (CAS 28198-05-2) is a high-purity analytical reference standard with the molecular formula C34H34N2O4 and a molecular weight of 534.64 g/mol.
The molecular framework of 9,10-Anthracenedione, 1,4-bis[(4-butylphenyl)amino]-5,8-dihydroxy- (C34H34N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
