Chemical Structure
Description
The occurrence of Tegoprazan Impurity 148 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Tegoprazan Impurity 148 (CAS CATO-C4X-2297148), a pharmacopoeial impurity reference standard (molecular formula C27H27N3O3, MW 441.52 g/mol) used for the identification and quantification of trace impurities in APIs.
Tegoprazan Impurity 148 (C27H27N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
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), Tegoprazan Impurity 148 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.
