1,4-Dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedicarboxylic acid bis(1-methylethyl) ester Chemical Properties,Usage,Production
Uses
3-Des(2-methoxyethyl) 3-(1-Methylethyl) Ester Nimodipine (Nimodipine EP Impurity B) can be used in synthetic preparation of dihydropyridinedicarboxylic acid esters by methylimidazolium trifluoroacetate-catalyzed Hantzsch cyclocondensation reaction of oxo-carboxylic acid esters with aldehydes and ammonium acetate. It can also be used as an analyte for analytical study in developing and optimizing a validated isocratic reversed-phase high-performance liquid chromatograhy separation of nimodipine and impurities in tablets using experimental. design methodology. It is an impurity of the drug Nimodipine (N478200).
