The racemic title compound, C3H5Br2NO, was crystallized from methanol. In the crystal, adjacent molecules are linked through N—HO hydrogen bonds, forming chains along the c-axis direction. These chains are linked through N—HO hydrogen bonds, forming an undulating two-dimensional network lying parallel to the bc plane. There are also short BrBr contacts present [3.514 (3) Å].

The title compound, {2-[(2-carbamoylethyl)amino]-3-methylpentanoic acid}, C9H18N2O3, is of interest with respect to its biological activity. It was formed during an addition reaction between acrylamide and the amino acid isoleucine. The crystal structure is a three-dimensional network built up by intermolecular N—HO and O—HN hydrogen bonds.
