3-{[(Benzyloxy)carbonyl]amino}butanoic acid

Abstract

In the title compound, C12H15NO4, the butyric acid group has a stretched trans conformation. The dihedral angle between the phenyl ring and the oxycarb­oxy­amino N—(C=O)—O—C plane is 56.6 (2)°. In the crystal, an inversion dimer is formed by a pair of O—H⋯O hydrogen bonds. The dimers are further linked by N—H⋯O hydrogen bonds between amide groups, forming a tape along the b axis.
