Desfluoro-ezetimibe 

Desfluoro-ezetimibe is a desfluoro impurity of Ezetimibe. Ezetimibe is a potent, metabolically stable cholesterol absorption inhibitor. Ezetimibe is a Niemann-Pick C1-like1 (NPC1L1) inhibitor, and is a potent Nrf2 activator^[1][2].

During the synthetic process development studies of Ezetimibe, an impurity was detected in the final product at levels ranging from 0.05% to 0.15% in reverse phase gradient high performance liquid chromatography (HPLC) method and its molecular weight is determined by LC–MS analysis. The impurity is Desfluoro-ezetimibe^[1].
