Chemical Structure
Description
1,4,5,8-Tetraamino-2,6-bis(3-chlorophenoxy)anthracene-9,10-dione (CAS 83424-40-2) is a high-purity analytical reference standard with the molecular formula C26H18Cl2N4O4 and a molecular weight of 521.35 g/mol.
The molecular framework of 1,4,5,8-Tetraamino-2,6-bis(3-chlorophenoxy)anthracene-9,10-dione (C26H18Cl2N4O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
