Chemical Structure
Description
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.
CATO supplies N-Nitroso Trimebutine Impurity 12 (CAS CATO-C4X-185812), a pharmacopoeial impurity reference standard (molecular formula C11H16N2O2, MW 208.26 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C11H16N2O2, N-Nitroso Trimebutine Impurity 12 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.26 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).
As a certified reference material (CRM), N-Nitroso Trimebutine Impurity 12 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.
