About Amoxicillin Impurity 101
Amoxicillin Impurity 101 is a specified impurity of Amoxicillin. 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 C20H20N4O4 and a molecular weight of 380.40, with the two-dimensional structure shown above. Because it shares the Amoxicillin scaffold, it is typically used to track process-related and degradation impurities of Amoxicillin 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.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
