چکیده
The title compound, C(10)H(14)N(4)O(6), crystallizes with two independent mol-ecules in the asymmetric unit. An extensive network of N-H⋯O and C-H⋯O inter-molecular hydrogen bonds stabilizes the crystal packing. One ethyl group is disordered over two positions; the site occupancy factors are 0.68 and 0.32.
