Linagliptin Impurity 57 CAS 2416949-69-2

Description

The occurrence of Linagliptin Impurity 57 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Linagliptin Impurity 57 (CAS 2416949-69-2) is a certified pharmaceutical impurity reference standard with the molecular formula C25H29N7O4 and a molecular weight of 491.54 g/mol.

Based on its molecular formula C25H29N7O4, Linagliptin Impurity 57 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 491.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
