Chemical Structure
Description
The molecular framework of 1,4,5,8-Tetraamino-2-bromo-6-(3-ethylphenoxy)anthracene-9,10-dione (C22H19BrN4O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
