Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 477.50 g/mol gives Tegoprazan Impurity 70 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tegoprazan Impurity 70 (CAS CATO-C4X-229770), a pharmacopoeial impurity reference standard (molecular formula C27H25F2N3O3, MW 477.50 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Tegoprazan Impurity 70 (C27H25F2N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 477.50 g/mol, it falls into the moderately-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.
As a certified reference material (CRM), Tegoprazan Impurity 70 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.
