Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dichloro-1,4-dihydroxyanthracene-9,10-dione.
6,7-Dichloro-1,4-dihydroxyanthracene-9,10-dione (CAS 1225-15-6) is a high-purity analytical reference standard with the molecular formula C14H6Cl2O4 and a molecular weight of 309.10 g/mol.
The molecular framework of 6,7-Dichloro-1,4-dihydroxyanthracene-9,10-dione (C14H6Cl2O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
