N-(4-(4-Fluorophenyl)-5-formyl-6-(1-methylethyl)-2-pyrimidinyl)-N-methylmethanesulfonamide

It helps in quality control, research, and understanding impurities related to Rosuvastatin’s manufacturing process, serving as a vital component in pharmaceutical development and testing. N-(4-(4-Fluorophenyl)-5-formyl-6-(1-methylethyl)-2-pyrimidinyl)-N-methylmethanesulfonamide is used mainly as a pharmaceutical reference standard, an impurity reference material, and a synthetic intermediate, especially in the production and analysis of the cholesterol-lowering drug Rosuvastatin (Crestor).
