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
介绍了氯法拉滨工艺杂质的鉴定及其随后的分离,合成和表征。发现了由氟代阿拉伯糖的N 6-附着至氯法拉滨产生的两种异构过程杂质。还合成并表征了与工艺杂质不同的氯法拉滨的碱降解产物。这些化合物是由糖部分,嘌呤环或两者的修饰产生的。提供了用于形成各种工艺杂质和降解产物的机械原理。
