Description
As a certified reference material (CRM), Alanyl Glutamine Impurity 5 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.
As a process- or degradation-related impurity, Alanyl Glutamine Impurity 5 (CAS CATO-C4X-19745, C8H13ClN2O4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Structurally, Alanyl Glutamine Impurity 5 (C8H13ClN2O4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 236.65 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
