Description
CATO supplies Tegoprazan Impurity 146 (CAS CATO-C4X-2297146), a pharmacopoeial impurity reference standard (molecular formula C18H20N2O4, MW 328.36 g/mol) used for the identification and quantification of trace impurities in APIs.
Tegoprazan Impurity 146 (C18H20N2O4) contains a flavonoid 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 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.
As a certified reference material (CRM), Tegoprazan Impurity 146 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.
