Tegoprazan Impurity 140 CAS CATO-C4X-2297140

Description

The occurrence of Tegoprazan Impurity 140 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tegoprazan Impurity 140 (CAS CATO-C4X-2297140) is a certified pharmaceutical impurity reference standard with the molecular formula C12H15N3O2 and a molecular weight of 233.27 g/mol.

Tegoprazan Impurity 140 (C12H15N3O2) contains an amino-acid-derived structure, 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).

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 140 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.
