Chemical Structure

N-Nitroso Dequalinium impurity 37 CAS CATO-C4X-193637 chemical structure

Description

As a process- or degradation-related impurity, N-Nitroso Dequalinium impurity 37 (CAS CATO-C4X-193637, C50H68N7O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

N-Nitroso Dequalinium impurity 37 (C50H68N7O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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), N-Nitroso Dequalinium impurity 37 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.
