Crystals of the title compound, C 8 H 9 NO 2 , were obtained from ethyl acetate. The structure consists of the acid in its zwitterionic form. In the crystal structure, each molecule interacts through strong N-HÁ Á ÁO hydrogen bonds with six adjacent molecules, yielding a three-dimensional network.

✦ Synopsis
The crystal structure of commercially available 4-hydroxyphenylacetic acid, C 8 H 8 O 3 , is non-centrosymmetric, with four hydrogen bonds between each molecule and adjacent molecules. The hydrogen bonds link the molecules in the crystal structure into an infinite three-dimensional framework.
