About Azilsartan Impurity 166
Azilsartan Impurity 166 is a specified impurity of Azilsartan. 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 C27H23N5O6 and a molecular weight of 513.5, with the two-dimensional structure shown above. Because it shares the Azilsartan scaffold, it is typically used to track process-related and degradation impurities of Azilsartan during method development, forced degradation and stability studies.
Computed from the structure, the compound has a monoisotopic mass of 513.1648 Da, a calculated LogP of 4.67, a topological polar surface area of 130.81 Ų. It presents 0 hydrogen-bond donors and 9 acceptors. 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.
