摘要：

The crystallographic characterization of the title molecule, C7H7F3N2O2, distinguishes it from its isomer, 5-methoxycarbonyl-1-methyl-4-trifluoromethylpyrazole, which is the major product in their joint synthesis. The bond lengths, except for C3-C4, are consistent with other molecules having substituents on the same ring positions. The pyrazole ring and the carboxy group plane are nearly coplanar.
