✦ Synopsis
The asymmetric unit of the title compound, C 9 H 9 N 3 O 4 , consists of two independent but similar molecules which are located on mirror planes. The molecules pack along the b axis with an interplanar distance of b/2. Intramolecular N-HÁ Á ÁO hydrogen bonds help to stablize the molecular structure.

In the crystal structure of the title compound, C 9 H 9 NO 4 , intermolecular O-HÁ Á ÁO hydrogen bonds link the molecules into centrosymmetric dimers.
In the title compound, C~11~H~13~NO~3~, the methoxycarbonyl group is rotated out of the plane of the 4-methoxybenzyl group. The conformation found in the crystal structure differs from that computed __in vacuo__, where the two groups are coplanar. The crystal structure is stabilized by van der Waals
