title: 1-Allyl-3-amino-1H-pyrazole-4-carboxylic acid.
abstract: The title compound, C(7)H(9)N(3)O(2), was prepared by alkaline hydrolysis of ethyl 1-allyl-3-amino-1H-pyrazole-4-carboxyl-ate. The crystal structure is stabilized by three types of inter-molecular hydrogen bond (N-H⋯O, N-H⋯N and O-H⋯N).
