title: 3-Methyl-2-propionamido-butanoic acid.
abstract: The reaction of propionyl isothio-cyanate with valine was found to give the title compound, C(8)H(15)NO(3), instead of the expected thio-urea product. The whole mol-ecule is non-planar and the carbonyl group is cis to the methyl-butanoic acid group across the C-N bond. Inter-molecular O-H⋯O and N-H⋯O hydrogen bonds build up a two-dimensional network developing parallel to (100).
