Chemical Structure
Description
Trelagliptin Impurity 29 (C18H21FN4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Trelagliptin Impurity 29 (CAS 1917324-15-2) is a certified pharmaceutical impurity reference standard with the molecular formula C18H21FN4O4 and a molecular weight of 376.38 g/mol.
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.
As a certified reference material (CRM), Trelagliptin Impurity 29 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.
