Chemical Structure
Description
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.
Alanyl Glutamine Impurity 20 TFA Salt (CAS 1508274-80-3) is a certified pharmaceutical impurity reference standard with the molecular formula C8H13N3O3C2HF3O2 and a molecular weight of 313.23 g/mol.
The molecular framework of Alanyl Glutamine Impurity 20 TFA Salt (C8H13N3O3C2HF3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Alanyl Glutamine Impurity 20 TFA Salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
