About Cefazolin Impurity 75
Cefazolin Impurity 75 is a specified impurity of Cefazolin. 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 C19H20N8O7S4 and a molecular weight of 600.67, with the two-dimensional structure shown above. Because it shares the Cefazolin scaffold, it is typically used to track process-related and degradation impurities of Cefazolin 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.
