Methyl 2-Methyl-6-(3-nitrophenyl)-4-oxo-2-cyclohexene-1-carboxylate + ~8% Ethyl 3-Methyl-3'-nitro-5-oxo-1,2,5,6-tetrahydro-[1,1'-biphenyl]-2-carboxylate is a byproduct in the synthesis of Methyl 2-Methyl-6-(3-nitrophenyl)-4-oxo-2-cyclohexene-1-carboxylate (M338310), a nicardipine impurity. Also, it is derived from Methyl Acetoacetate (O848425), which is a chemical reagent used in the synthesis of pharmaceuticals. It participates in the Biginelli reaction, forming molecules including dihydropyrimidinones.
