Chemical Structure
Description
The molecular framework of 2-Chloro-1,8-diphenoxyanthracene-9,10-dione (C26H15ClO4) is characterized by a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-Chloro-1,8-diphenoxyanthracene-9,10-dione (CAS 61601-41-0) is a high-purity analytical reference standard with the molecular formula C26H15ClO4 and a molecular weight of 426.85 g/mol.
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.
As a certified reference material (CRM), 2-Chloro-1,8-diphenoxyanthracene-9,10-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
