Chemical Structure

4-(4-(Benzyloxy)-2-methylbenzoyl)-1-(2-(diethylamino)ethyl)-5-(4-ethoxyphenyl)-3-hydroxy-1H-pyrrol-2(5H)-one CAS 488805-01-2 chemical structure

Description

The molecular framework of 4-(4-(Benzyloxy)-2-methylbenzoyl)-1-(2-(diethylamino)ethyl)-5-(4-ethoxyphenyl)-3-hydroxy-1H-pyrrol-2(5H)-one (C33H38N2O5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
