(Rac)-5-Keto Fluvastatin is primarily utilized in research and development within the pharmaceutical industry. It serves as an intermediate or reference compound in the synthesis and study of fluvastatin, a medication used to lower cholesterol levels. Researchers employ it to explore metabolic pathways, enzymatic interactions, and the biochemical mechanisms of statins. Additionally, it aids in the development of analytical methods for quality control and the identification of impurities in fluvastatin production. Its role is crucial in advancing the understanding of statin pharmacology and improving therapeutic formulations.
