title: Ethyl 3-nitro-4-(n-propyl-amino)benzoate.
abstract: In the mol-ecule of the title compound, C(12)H(16)N(2)O(4), an intra-molecular N-H⋯O hydrogen bond results in the formation of a six-membered ring having an envelope conformation. In the crystal structure, a bifurcated intra/intermolecular N-H⋯(O,O) hydrogen bond generates inversion dimers.
