Chemical Structure
Description
The molecular framework of 4-((2,5-Dichlorophenyl)amino)-2-(4-methylpiperazin-1-yl)-4-oxobutanoic acid (C15H19Cl2N3O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
4-((2,5-Dichlorophenyl)amino)-2-(4-methylpiperazin-1-yl)-4-oxobutanoic acid (CAS 900011-70-3), molecular formula C15H19Cl2N3O3 and molecular weight 360.24 g/mol, is a CATO reference standard with documented purity and traceability.
