Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 203.20 g/mol gives Alanyl Glutamine Impurity 45 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Alanyl Glutamine Impurity 45 (CAS CATO-C4X-197445, C7H13N3O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Alanyl Glutamine Impurity 45 (C7H13N3O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Alanyl Glutamine Impurity 45 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
