About Lamivudine Impurity 42
Lamivudine Impurity 42 is a specified impurity of Lamivudine. 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 C8H9N3O4S and a molecular weight of 243.24, with the two-dimensional structure shown above. Because it shares the Lamivudine scaffold, it is typically used to track process-related and degradation impurities of Lamivudine 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: -20±5℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
