About N-Nitroso-Nebivolol
N-Nitroso-Nebivolol is a specified impurity of Nebivolol. It has no single publicly registered CAS number, so it is defined by the structure and molecular formula below.
The compound is characterised by its molecular formula C22H24F2N2O5 and a molecular weight of 434.43, with the two-dimensional structure shown above. Because it shares the Nebivolol scaffold, it is typically used to track process-related and degradation impurities of Nebivolol during method development, forced degradation and stability studies.
Computed from the structure, the compound has a monoisotopic mass of 434.1653 Da, a calculated LogP of 2.76, a topological polar surface area of 91.59 Ų. It presents 2 hydrogen-bond donors and 6 acceptors. The structure carries 4 defined stereocentres, which is relevant wherever a stereochemically defined standard is required. These values are commonly used to anticipate chromatographic retention and to plan ionisation conditions during method development.
Each pack ships with a certificate of analysis together with the supporting analytical data — HNMR, MS and HPLC or GC traces — so the material can be released straight into your own QC workflow.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
