N-((S)-4-amino-1-carboxy-4-oxobutyl)-N-glycylglycyl-D-glutamine CAS CATO-CPTD789027

Description

The molecular framework of N-((S)-4-amino-1-carboxy-4-oxobutyl)-N-glycylglycyl-D-glutamine (C14H23N5O8) 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.

As a process- or degradation-related impurity, N-((S)-4-amino-1-carboxy-4-oxobutyl)-N-glycylglycyl-D-glutamine (CAS CATO-CPTD789027, C14H23N5O8) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
