- Isolation, synthesis, and characterization of impurities and degradants from the clofarabine process
-
The identification of clofarabine process impurities and their subsequent isolation, synthesis, and characterization is described. Two isomeric process impurities resulting from N6-attachment of a fluoroarabinose to clofarabine were found. Clofarabine's base degradation products, which were different from the process impurities, were also synthesized and characterized. These compounds resulted from modifications to the sugar moiety, the purine ring, or both. A mechanistic rationale for the formation of the various process impurities and degradation products is provided.
