Fluvastatin is a synthetic statin compound, chemically designated as (3R,5S,6E)-7-[3-(4-fluorophenyl)-1-[methanesulfonyl(methyl)amino]-1H-indol-2-yl]-3,5-dihydroxyhept-6-enoic acid. It functions as a competitive inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase, the rate-limiting enzyme in cholesterol biosynthesis. This high-purity (≥98%) reagent is used in pharmaceutical research, as a reference standard for analytical testing (e.g., HPLC, NMR, IR), in studies of lipid metabolism and atherosclerosis, and in the development of cholesterol-lowering drugs. It appears as a pale yellow solid and conforms to structural standards via spectroscopic analysis. Not for human therapeutic use; handle with appropriate laboratory safety precautions.
