title: 4-Hydr-oxy-3-nitro-phenyl penta-noate.
abstract: In the title compound, C(11)H(13)NO(5), an intra-molecular O-H⋯O hydrogen bond is formed between the hydr-oxy and the nitro groups, which results in the formation of a six-membered ring. The valer-oxy group shows a torsioned conformation, and connects to the aryl ring with a C-C-O-C torsion angle of 102.34 (1)°.
