✦ Synopsis

Reactions of 4-nitro-3(5)-pyrazolecarboxylic acid dipotassium salt with different methylating agents in various solvents have been investigated to improve the synthesis of isomeric 1-methyl-4-nitro-3-and -5-pyrazolecarboxylic acids.

The molecules of the title compound, C~5~H~5~N~3~O~4~, are approximately planar. The nitro group makes a dihedral angle of 1.3 (4)° with the plane of the six-membered ring. This coplanar disposition is a reason for the changes in valence angles in the vicinity of the nitro group. Molecules are conne
