Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Liraglutide Impurity 26.
Liraglutide Impurity 26 (CAS CATO-C4X-199226) is a certified pharmaceutical impurity reference standard with the molecular formula C172H265N43O51 and a molecular weight of 3751.20 g/mol.
Structurally, Liraglutide Impurity 26 (C172H265N43O51) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 62.0, corresponding to approximately 62 ring(s) or double-bond equivalent(s). With a molecular weight of 3751.20 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).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Liraglutide Impurity 26 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.
