About Letrozole Impurity 10
Letrozole Impurity 10 is a specified impurity of Letrozole. 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 C17H12N4O2 and a molecular weight of 304.30, with the two-dimensional structure shown above. Because it shares the Letrozole scaffold, it is typically used to track process-related and degradation impurities of Letrozole during method development, forced degradation and stability studies.
Each pack ships with a certificate of analysis reporting purity of 95%+ 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. Recommended storage: 2℃ ~ 8℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
