Synthesis and characterization of potential impurities in Fenofibrate drug substance

Fenofibrate is used to treat high levels of cholest erol and triglyceride in the blood. In the present study, eight process related impurities of Fenofibrate drug were synthesized and characterized by their respective spectral data (IR, MS and 1 H-NMR). The identification of these impurities shou ld be useful for quality control in the manufacture of Fenofibrate.
