As a certified reference material (CRM), Alogliptin Impurity 39 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.
Alogliptin Impurity 39 (CAS 6297-80-9) is a certified pharmaceutical impurity reference standard with the molecular formula C4H6Cl2N2O and a molecular weight of 169.01 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Alogliptin Impurity 39 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
