Description
N-Nitroso Buspirone EP Impurity A-d8 (CAS CATO-C4X-125841) is a certified pharmaceutical impurity reference standard with the molecular formula C8H3D8N5O and a molecular weight of 201.26 g/mol.
Structurally, N-Nitroso Buspirone EP Impurity A-d8 (C8H3D8N5O) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 201.26 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Buspirone EP Impurity A-d8 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.
