Lansoprazole Impurity 20 CAS CATO-C4X-111320

Description

Compared with other compounds in its class, the molecular weight of 205.18 g/mol gives Lansoprazole Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Lansoprazole Impurity 20 (CAS CATO-C4X-111320), a pharmacopoeial impurity reference standard (molecular formula C9H10F3NO, MW 205.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H10F3NO, Lansoprazole Impurity 20 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 205.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Lansoprazole Impurity 20 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.
