Chemical Structure
Description
The occurrence of Xanomeline Impurity 8 is closely related to a nitrile group, sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
As a process- or degradation-related impurity, Xanomeline Impurity 8 (CAS 131987-88-7, C7H5N3S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Based on its molecular formula C7H5N3S, Xanomeline Impurity 8 contains a nitrile group, sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 163.20 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), Xanomeline Impurity 8 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.
