Chemical Structure
Description
The molecular framework of Methyl 4-(4-chlorophenyl)-1-(3,4-dimethoxyphenethyl)-2-methyl-1H-pyrrole-3-carboxylate (C23H24ClNO4) is characterized by a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
