Chemical Structure
Description
Structurally, Linagliptin impurity 166 (C50H56N16O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 31.0, corresponding to approximately 31 ring(s) or double-bond equivalent(s). With a molecular weight of 945.08 g/mol, it falls into the high-molecular-weight range. 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).
Linagliptin impurity 166 (CAS CATO-C4X-1101166) is a certified pharmaceutical impurity reference standard with the molecular formula C50H56N16O4 and a molecular weight of 945.08 g/mol.
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 Linagliptin impurity 166 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.
