Atorvastatin 3-Fluoro Analog

Atorvastatin 3-Fluoro Analog is a structurally modified derivative of atorvastatin, featuring a fluorine atom substituted at the 3-position of the phenyl ring. This substitution alters the electronic and steric properties of the parent molecule, impacting its metabolic stability and pharmacokinetic profile. The compound retains the core pyrrole-lactone scaffold and the hydroxymethyl group essential for HMG-CoA reductase interaction. Its fluorinated aromatic ring introduces a unique dipole moment, enhancing differentiation from related impurities via chromatographic methods. This compound serves as a critical HPLC reference standard for quantifying process-related impurities in atorvastatin formulations.
