Chemical Structure
Description
The molecular framework of 1-Amino-8-chloro-2-(p-tolylamino)anthracene-9,10-dione (C21H15ClN2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-Amino-8-chloro-2-(p-tolylamino)anthracene-9,10-dione (CAS 88653-24-1) is a high-purity analytical reference standard with the molecular formula C21H15ClN2O2 and a molecular weight of 362.81 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.
