Ciprofibrate is a medication used to lower cholesterol and triglyceride levels in the blood. However, during the manufacturing process of ciprofibrate, impurities may be present in the final product. These impurities can affect the safety and efficacy of the medication, which is why it is important to monitor and control their levels. Some common ciprofibrate impurities include isomers, related compounds, and residual solvents. Analytical methods such as high-performance liquid chromatography (HPLC) and gas chromatography (GC) are used to identify and quantify these impurities.
